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

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?

  • 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

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.

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.

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

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..

If you have opened the command prompt(cmd) to run the jar on current folder,then the error will come as above.so close the command prompt and try maven clean and install,it will work definitely.

For IntelliJ users, 

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

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.

For me clearing the previous maven tasks worked. enter image description here

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

Best luck!

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.
