Maven - 未能执行目标 org.apache.maven.plugins:maven-clean-plugin:2.4.1:clean

Question

I've a problem with the following dependency in my pom.xml where org.springframework.version = 3.1.0.RELEASE:

<!-- Spring MVC framework -->
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-webmvc</artifactId>
    <version>${org.springframework.version}</version>
</dependency>

When I execute the command line 'mvn clean install', I've the following error:

 [INFO] BUILD FAILURE
 [INFO] ------------------------------------------------------------------------

By seeing on http://mvnrepository.com/artifact/org.springframework/spring-webmvc/3.1.0.RELEASE , there aren't any errors in my dependency.

Do you have any solutions?

Answer 1

Failed to delete C:\EclipseProjects\myGoogleAppEngine\target\myGoogleAppEngine-0.0.1-SNAPSHOT\WEB-INF\lib\spring-webmvc-3.1.0.RELEASE.jar

Because of the path C:\EclipseProjects i guess you have eclipse running on that project. If you application runs, you cannot clean the output, because it may be in use.

Stop the application and maybe eclipse and try again.

Answer 2

删除任务管理器中的java.exe进程并重新执行。它对我有用。

Answer 3

确保您对文件夹的权限是正确的。因为我遇到了同样的问题，并且在更改文件夹和文件的所有权后，问题就解决了。

Answer 4

• Solution 1: Sometimes the build fails because, the target folder cannot be deleted. (It might be open in the backend due to the previous builds.)

  -> Open Task Manager

  -> In the Process tab

  -> Do "End Process" for the running "java.exe" processess

• Solution 2:

  -> Restart eclipse

  -> Perform Maven Build with command : clean install -DSkipTests

Try changing the permissions on the workspace folder. Make sure you have sufficient permissions to delete files in this folder. I faced the same problem and when i provided full control over the project folder (changing windows security permissions), it worked fine for me.

Just to update, this morning it again started giving the same error even when i have given all the permissions. So i tried to delete the particular file (pointed in the error logs) manually to find out what's exactly the problem.

I got the error "can not delete file because it's in use by Java TM SE". So the file was being used by java process due to which eclipse was not able to delete it.

I closed the java process from task manager and after that it worked fine. Although its kinda hectic to close the java process every time I need to execute my project, its the working solution right now for me.

Answer 6

Kill the "Java (TM)" process from processes in your computer. Re-run the mvn command. It should work now.

Answer 7

Reason and solution-

Everything happens for a reason :)

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-clean-plugin:3.1.0:clean (default-clean) on project

• The reason of this problem is that the target folder is already in use. That means any jar or any war or any application is using that target folder

Solution- 1) Check the war and jar (also check jar if any running in background), terminate it.

2) if u have opened command prompt (cmd), and are using that path to execute the jar, close it or change the path in cmd. This was the reason in my case. Do check this.

Once u do this , u would be able to delete the contents of the target folder and and can also perform maven clean and maven install.

Answer 8

On Windows, I got "Unable to delete directory". What's wrong? For instance, clean could fail if you already have opened a command line with target as the current dir. Windows locks some ressources and you need to close the handles on these ressources.

This works for me.

Answer 9

if you run a server instance, stop it for the time of build process. worked for me.

Answer 10

In my case, it was Subversion, TortoiseSVN clinging to those files, so I just clicked on SVN in the Eclipse menu and then disconnect. Worked for me.

Answer 11

如果您打开它试图删除的目录，那么您也将面临同样的错误，因此请先关闭该文件夹。

Answer 12

就我而言，我更改了所有文件的所有者并且它有效。

sudo chown -R anuruddha *

Answer 13

For me it worked by closing the Eclipse and using the command line to build the project. Seems like Eclipse had taken a lock on the files.

Answer 14

you may need to check whether the settings.xml file is correct. such as user name, password, third party url.

Answer 15

I've noticed that sometimes eclipse somehow picks up some of the jars and keeps a lock on them (in Windows only) and when you try to do mvn clean it says:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-clean-plugin:2.2:clean (default-clean) on project

The only solution so far is to close eclipse and run the mvn build again.

And these are random jars - it can pick up anything it wants... Why that happens is a mystery to me. Probably eclipse opens the jars when you do Type Search or Resource Search and forgets to close them / release the file handlers..

Answer 16

如果你已经打开命令提示符（cmd）在当前文件夹运行jar，那么错误会如上。所以关闭命令提示符并尝试maven clean and install，它肯定会工作。

Answer 17

For IntelliJ users,

1. File -> Invalidate your cache/restart the ide 
2. clean install -DSkipTests

Answer 18

In my case in my background I was inside the folder from command prompt after closing the command prompt. I was able to run the maven clean command.

Answer 19

For me clearing the previous maven tasks worked.

After clearing this, from eclipse project properties > run as > maven > clean followed by try maven build.

Best luck!

Answer 20

For me manually deleting the files in target folder using sudo worked. It's the need for root permission to delete files in the target folder.
