无法解析 org.apache.maven.archetypes 的版本

Question

I have configured maven3.0.3 in my local machine. Have installed m2e eclipse plugin. But when i try to create a new maven project using maven-archetype-webapp, i get the following exception.

 Could not resolve archetype org.apache.maven.archetypes:maven-archetype-webapp:RELEASE    from any of the configured repositories.
 Could not resolve artifact org.apache.maven.archetypes:maven-archetype- webapp:pom:RELEASE
 Failed to resolve version for org.apache.maven.archetypes:maven-archetype- webapp:pom:RELEASE: Could not find metadata org.apache.maven.archetypes:maven-archetype- webapp/maven-metadata.xml in local ([HOME]/.m2/repository)
 Failed to resolve version for org.apache.maven.archetypes:maven-archetype-  webapp:pom:RELEASE: Could not find metadata org.apache.maven.archetypes:maven-archetype-  webapp/maven-metadata.xml in local ([HOME]/.m2/repository)

I do some processing behind a proxy and the proxy configurations are updated in {HOME}/.m2/settings.xml and M2_HOME/conf/settings.xml.

The archetype generate command works fine in command line. It downloaded the dependencies through proxy.

Any help is greatly appreciated.

Edit 05-10-2012 While creating a new Maven Web project in eclipse, the archetype "maven-archetype-webapp" version is displayed as RELEASE. Is this in anyway linked?

Answer 1

I had the same problem. I fixed it by adding the maven archetype catalog to eclipse. Steps are provided below:

1. Open Window > Preferences
2. Open Maven > Archetypes
3. Click 'Add Remote Catalog' and add the following:
   • Catalog File: http://repo1.maven.org/maven2/archetype-catalog.xml
   • Description: maven catalog

Answer 2

I found the following tutorial very useful.

Step1: The maven command used to create the web app: mvn archetype:generate -DgroupId=test.aasweb -DartifactId=TestWebApp -DarchetypeArtifactId=maven-archetype-webapp

Step2: The following entry was added onto the project's pom.xml.

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>2.0.2</version>
    <configuration>
    <source>1.6</source>
    <target>1.6</target>
    </configuration>
</plugin>

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-eclipse-plugin</artifactId>
    <configuration>
    <wtpapplicationxml>true</wtpapplicationxml>
    <wtpversion>1.5</wtpversion>
    <downloadSources>true</downloadSources>
    <downloadJavadocs>true</downloadJavadocs>
        <classpathContainers>
            <classpathContainer>
                org.eclipse.jst.j2ee.internal.web.container
            </classpathContainer>
            <classpathContainer>
                org.eclipse.jst.j2ee.internal.module.container
            </classpathContainer>
        /classpathContainers>
        <additionalProjectFacets>
            <jst.web>2.5</jst.web>
            <jst.jsf>1.2</jst.jsf>
        </additionalProjectFacets>
    </configuration>
</plugin>

Step3: Run the maven command to convert into eclipse project format. mvn eclipse:clean eclipse:eclipse

Step4: Import the project onto eclipse as Existing Maven project.

Answer 3

Read carefully about the reason.

"Failed to resolve version for org.apache.maven.archetypes:maven-archetype- webapp:pom:RELEASE: Could not find metadata org.apache.maven.archetypes:maven-archetype- webapp/ maven-metadata.xml in local"

So all you need to do is download the maven-metadata.xml to your {HOME}.m2\\repository

That's it.

Answer 4

You do need to have a settings.xml linked under user settings (Located in preferences under maven)

But, if that doesn't fix it, like it didn't for many of you. You also have to delete the directory:

.m2/repository/org/apache/maven/archetypes/maven-archetype-quickstart

then quit eclipse and try again.

This is what solved my problem.

Answer 5

If you are using eclipse, you can follow the steps here ( maven in 5 min not working ) for getting your proxy information. Once done follow the steps below:

1. Go to Maven installation folder C:\\apache-maven-3.1.0\\conf\\
2. Copy settings.xml to C:\\Users\\[UserFolder]\\.m2

3. Modify the proxy in settings.xml based on the info that you get from the above link.

    <proxy> <active>true</active> <protocol>http</protocol> <host>your proxy</host> <port>your port</port> </proxy> 

4. Open eclipse

5. Go to: Windows > Preferences > Maven > User Settings

6. Browse the settings.xml from .m2 folder

7. Click Update Settings

8. Click Reindex

9. Apply the changes and Click OK

You can now try to create Maven Project in Eclipse

Answer 6

Go to Windows-> Preference-> Maven -> User settings

Select settings.xml of Maven

Restart Eclipse

Answer 7

I had a similar problem building from just command line Maven. I eventually got past that error by adding -U to the maven arguments.

Depending on how you have your source repository configuration set up in your settings.xml, sometimes Maven fails to download a particular artifact, so it assumes that the artifact can't be downloaded, even if you change some settings that would give Maven visibility to the artifact if it just tried. -U forces Maven to look again.

Now you need to make sure that the artifact Maven is looking for is in at least one of the repositories that is referenced by your settings.xml. To know for sure, run

mvn help:effective-settings

from the directory of the module you are trying to build. That should give you, among other things, a complete list of the repositories you Maven is using to look for the artifact.

I too had same problem but after searching solved this. go to menu --> window-->preferences-->maven-->Installations-->add--> in place of installation home add path to the directory in which you installed maven-->finish-->check the box of newly added content-->apply-->ok. now create new maven project but remember try with different group id and artifact id.

Answer 9

I had the same problem i solved it by only adding remote catalog in eclipse go to Window -> Preferences ->Maven ->Archetypes ->click on add remote Catalog then a window will open in that paste
http://repo.maven.apache.org/maven2/archetype-catalog.xml in that catalog file then hit ok restart eclipse now all working fine

Create New User Environment Variables:

MAVEN_HOME=D:\apache-maven-3.5.3

MAVEN=D:\apache-maven-3.5.3\bin

MAVEN_OPTS=-Xms256m -Xmx512m

Appened below in Path variable (System Variable):

;D:\apache-maven-3.5.3\bin;

Answer 12

这对我有用： - 导航到windows-> preferences-> maven并检查“下载工件源”并单击“应用”。

Answer 13

No need to do all above lengthy steps.

Simply delete c:\\Users\\.m2\\Repository\\org folder

Maven will automatically downloads what it needs

Answer 14

I simple use below steps:

Create Maven project -> check checkobox -> "Create a simple project (skip archetype selection)"

It works for me

Answer 15

我从这里下载了jar和pom，并将它们放在这里：

\.m2\repository\org\apache\maven\archetypes\maven-archetype-quickstart\1.1\

Answer 16

我也有同样的错误....我发现我的互联网连接已经关闭所以eclipse无法下载webapps原型的存储库，当我得到互联网连接时，我刚刚创建了maven项目与webapps archetypes和我的eclipse下载了存储库及其做...

Answer 17

This is 100% working:

• Delete the .m2 folder which is present in your Desktop>User
• connect your pc to the Internet
• Create your maven project again

Thats it, hope it helps

Answer 18

Try, It worked for = I just removed "archetypes" folder from below location

C:\Users\Lenovo.m2\repository\org\apache\maven

But you may change following for experiment - download latest binary zip of Maven, add to you C:\ drive and change following....

Change Proxy

 <proxy>
          <id>optional</id>
          <active>true</active>
          <protocol>http</protocol>
          <username></username>
          <password></password>
          <host>10.23.73.253</host>
          <port>8080</port>
          <nonProxyHosts>local.net|some.host.com</nonProxyHosts>
        </proxy>

Answer 19

The problem may also come from that you haven't set MAVEN_HOME environment variable. So the Maven embedded in Eclipse can't do its job to download the archetype.Check if that variable is set upfront.
