Maven 全新安装：无法执行目标 org.apache.maven.plugins:maven-resources-plugin:3.20。

Question

I don´t know what´s the problem. Trying to install maven for a college project. I already installed maven as instructed here . Picture Environmental Variables , maven version in cmd And I also tried to delete the.m2 file. When I try to install maven over the plugin in InteliJ, I get the message: "process terminated" with no extra info. Then I tried to install over the terminal with mvn clean install and i got this.

Answer 1

It might be a new bug coming with some latest release of Spring-boot (and then: Spring ).

I had it. The workaround is to put in your pom.xml this corrected dependency:

<!-- Pour contourner un bug à la génération par Spring-boot 2.4.x : 
Failed to execute goal org.apache.maven.plugins:maven-resources-plugin:3.2.0:resources (default-resources) on project application-etude: Input length = 1 -->               
<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-resources-plugin</artifactId>
    <version>3.1.0</version>
</plugin>               

Answer 2

The root cause of the exception is that some resources contain resources which should not filtered (aka binary). The correct solution is to define an exclude for file extensions which should not filtered like the following :

<project>
  ...
  <build>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-resources-plugin</artifactId>
        <configuration>
          <nonFilteredFileExtensions>
            <nonFilteredFileExtension>pdf</nonFilteredFileExtension>
            <nonFilteredFileExtension>swf</nonFilteredFileExtension>
          </nonFilteredFileExtensions>
        </configuration>
      </plugin>
    </plugins>
    ...
  </build>
  ...
</project>

Answer 3

I had the same problem and fixed it by adding in the pom.xml:

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>

Here is the comment that help me solved the problem: https://github.com/spring-projects/spring-boot/issues/24346#issuecomment-740345146

Answer 4

In my case, the error happened because I had properties files encoded with ANSI, while maven was trying to use UTF-8. I fixed it by converting my properties files to UTF-8, and then running mvn clean compile .

Answer 5

In my case, the error was due to accents on "application.properties"

It would certainly be far easier to fix such errors if the tool simply gave a message saying that a certain file contains invalid characters...

For the record, the relevant log part, after running mvn clean package -e -X , was this one:

[DEBUG] Using 'UTF-8' encoding to copy filtered resource 'application.properties'.
[DEBUG] filtering D:\Java\PreVendaAPI\src\main\resources\application.properties to D:\Java\PreVendaAPI\target\classes\application.properties
[INFO] ------------------------------------------------------------------------
[INFO] BUILD FAILURE
[INFO] ------------------------------------------------------------------------

Answer 6

I faced the same issue, and fixed it using the below changes in my pom.xml build plugin.

<project>
...
    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-resources-plugin</artifactId>
                <version>3.1.0</version>
            </plugin>
        </plugins>
    </build>
</project>

Answer 7

You need exclude binary resourses.

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-resources-plugin</artifactId>
    <version>3.2.0</version>
    <configuration>
        <propertiesEncoding>UTF-8</propertiesEncoding>
        <nonFilteredFileExtensions>
            <nonFilteredFileExtension>xls</nonFilteredFileExtension>
            <nonFilteredFileExtension>xlsx</nonFilteredFileExtension>
        </nonFilteredFileExtensions>
    </configuration>
</plugin>

Answer 8

I had the same error. After removing german umlauts ('ü') from comments in my propertie files, they should be filtered, the problem is gone!

Answer 9

Some of your resources contains a character not in the ISO-8859-1 codepage, and this can cause disturbance here:

   at java.io.Reader.read (Reader.java:229)
   at org.apache.maven.shared.utils.io.IOUtil.copy (IOUtil.java:199)

A typical error might be an accentuated character in a.properties file.

Answer 10

The problem is with the maven-resources-plugin. Newer versions of this plugin are less lenient than the older versions. Unfortunately, the error message that is displayed when the Maven build fails (Input length = 1) is only helpful if you recognize it from previous experience with character set problems in Java.

You can add some options to the Maven build command so it will display DEBUG level output and a full stacktrace on build failures. Try this as your first step in diagnosing the root cause:

mvn -e -X clean test

It will output a LOT of info to the console during the build with these options turned on. Just wait until the failure happens and check the end of the console output. You should see a full stacktrace at the end that will make more sense. Just before the stacktrace, you should also see the name of the file in your project that caused the error. For me, I saw output like this:

directory C:\GITROOT\conndev\repos\conn-lamp-server\src\test\resources
excludes []
includes []
[DEBUG] ignoreDelta true
[INFO] Copying 3 resources
[DEBUG] Copying file application-inttest.properties
[DEBUG] file application-inttest.properties has a filtered file extension
[DEBUG] Using 'UTF-8' encoding to copy filtered resource 'application-inttest.properties'.
[DEBUG] filtering C:\GITROOT\conndev\repos\conn-lamp-server\src\test\resources\application-inttest.properties to C:\GITROOT\conndev\repos\conn-lamp-server\target\test-classes\application-inttest.properties
[DEBUG] Copying file DummyExcelFile.xls
[DEBUG] file DummyExcelFile.xls has a filtered file extension
[DEBUG] Using 'UTF-8' encoding to copy filtered resource 'DummyExcelFile.xls'.
[DEBUG] filtering C:\GITROOT\conndev\repos\conn-lamp-server\src\test\resources\DummyExcelFile.xls to C:\GITROOT\conndev\repos\conn-lamp-server\target\test-classes\DummyExcelFile.xls
[INFO] ------------------------------------------------------------------------

[INFO] Total time:  37.927 s
[INFO] Finished at: 2022-04-26T10:11:09-03:00
[INFO] ------------------------------------------------------------------------

Now I know that a file in my test resources directory was the problem:

src\test\resources\DummyExcelFile.xls

Older versions of the resources plugin must have been quietly suppressing the problem. I won't include the full stacktrace here, but this is the important line from the stacktrace:

Caused by: java.nio.charset.MalformedInputException: Input length = 1

I've seen this before. It happens when a text file cannot be read by a Java 'reader' class because the file contains one or more characters that are invalid for the character set used by the reader. In my case, it was trying to read a binary file as text, so that was never going to work. The same problem could happen if you have a text file that contains unusual characters (such as those from European languages with accents) and those characters are not valid for the character set you are using (such as UTF-8). All these problems can be solved with some POM configuration.

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-resources-plugin</artifactId>
            <configuration>
                <propertiesEncoding>UTF-8</propertiesEncoding>
                <nonFilteredFileExtensions>
                    <nonFilteredFileExtension>xls</nonFilteredFileExtension>
                    <nonFilteredFileExtension>zip</nonFilteredFileExtension>
                </nonFilteredFileExtensions>
            </configuration>
        </plugin>

If you are using a different character set from UTF-8, just substitute yours in the XML snippet above. Do the same for any file extensions that you want the maven-resource-plugin to ignore when it does filtering.

Note that I have intentionally omitted the <version> for the maven-resources-plugin block above. This is because I am using the spring-boot-starter-parent in my POM and the version of many dependencies is inherited from the parent. If you do not use a parent, then you will have to explicitly set the version you want to use.

This message came up today, here is what I did to resolve it:

I used mvn to analyze the resources like this:

mvn -X process-test-resources

This way mvn returned the name of the file wich was causing the error:

[DEBUG] filtering .../messages.properties
[INFO] ------------------------------------------------------------------------
[INFO] BUILD FAILURE
[INFO] ------------------------------------------------------------------------
[INFO] Total time:  x
[INFO] Finished at: y
[INFO] ------------------------------------------------------------------------
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-resources-plugin:3.2.0:resources (default-resources) on foo: Input length = 1 -> 

Turned out messages.properties contained special chars which had not been escaped properly. So I escaped them in the i18n-file and after that I was able to build again.

Answer 12

I Belive that error heppens because have some problems of compatibility R: The possible solution is to insert this plugin in pom.xml

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-resources-plugin</artifactId>
    <version>3.1.0</version>
</plugin>

Answer 13

For me stopping the server helped

(On Windows 10) npx kill-port your_port

Answer 14

By default, maven-resources-plugin uses project.build.sourceEncoding when filtering resources (which defaults to UTF-8 ).

The java standard for .properties files requires ISO-8859-1 encoding.

To resolve this, you can explicitely configure how .properties Files should be filtered:

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-resources-plugin</artifactId>
  <version>3.2.0</version>
  <configuration>
    <propertiesEncoding>ISO-8859-1</propertiesEncoding>
  </configuration>
</plugin>

This is also described in the official documentation of the plugin: https://maven.apache.org/plugins/maven-resources-plugin/examples/filtering-properties-files.html

Estava com um problema semelhante em um projeto spring, a resolução foi essa, mudei a versão do plugin maven, que no meu arquivo pom.xml não tinha, adicionei e testei a versão 3.1.0 e deu certo.

    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-resources-plugin</artifactId>
            <version>3.1.0</version>
        </plugin>

        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
        </plugin>
    </plugins>

Answer 16

I think you are defining application.property and application.yml at the same time. If you want to use both of them, please try plug the maven-resources-plugin

Answer 17

Using this dependency solved this problem of mine

<dependency>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-resources-plugin</artifactId>
    <version>3.2.0</version>
</dependency>

Answer 18

I had the same error when writing non utf-8 characters in a comment in application.properties file. I deleted those characters and it's working !

Answer 19

<properties>
    <java.version>1.8</java.version>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>

Use this in application.properties file that will definetly work.
