maven... Failed to clean project: Failed to delete ..\org.ow2.util.asm-asm-tree-3.1.jar

JavaEclipseSpringMavenSpring Tool-Suite

Java Problem Overview

I use STS(spring tool suite) + maven plugin.

Every time when I run my application using maven-clean I see following error:

[INFO] Scanning for projects...

I have to close STS and go to C:\Users\Nikolay_Tkachev\workspace\HHSystem\UI\target and delete org.ow2.util.asm-asm-tree-3.1.jar

After starting STS again it works, but this is a hassle.

Can you help me with this problem?

UPDATE
for Kalathoki L.

I run maven-clean from this state:

I see same behaviour from the command line as from the eclipse plugin

If I watch unlocker when STS is running I see

Stop your server before you start to clean.

Stopping a server

You can stop the server from the Servers view.

To stop the server:

  1. In the Servers view ( Window > Show View > Other > Server > Servers > OK), select the server that you want to stop.

  2. Click the Stop the server this icon in the toolbar. In the Servers view, the status of the server changes to Stopped.

  3. If for some reason the server fails to stop, you can terminate the process as follows:

a. Switch to the Debug perspective.

b. In the Process view, select the server process that you want to stop.

c. Click the Terminate This is an image of the Terminate icon in the toolbar.

Note: When terminating a server, the server process will end and the server will not go through the normal routine of stopping, for example calling the destroy() method on a servlet.

You may also try try -Dmaven.clean.failOnError=false (from [Maven FAQ][1])

[1]: http://maven.apache.org/plugins/maven-clean-plugin/faq.html "Maven FAQ"

Solution 3 - Java

Delete the java.exe process in Task Manager and run mvn clean install.It worked for me.

Solution 4 - Java

Your problem is that a running process within STS is using files located in your target directory while you execute a mvn clean command. Maven will be unable to delete these files (since other processes are still accessing them) and thus fail with that error.

Try to stop all processes (tests, servers, applications) from within STS before running Maven console commands. Look out: This behaviour might also appear if STS is cleaning up the projects and thus re-compiles the sources, and not running a process.

Solution 5 - Java

Close the target folder and its file you have opened before mvn clean

Solution 6 - Java

Probably there are many processes that use sources compiled, could be a server, an old maven instruction or IDE. Sure terminate all processes, stop the server and then execute maven again. If the problem persists, you should close java.exe process.

Regards!

Solution 7 - Java

Try disabling Project->Build Automatically.

As Scorpio suggested, there's a process running that's got a lock on a file somewhere.

I have a large multi-module maven project that regularly fails on clean and this resolves it for me. I re-enable Build Automatically when I'm done.

Solution 8 - Java

I have same problem and this

mvn clean install -U

command fixed the error.

Solution 9 - Java

Summary : Use an external script (batch file) that a) stops the server and b) Unlocks the .jar file before running maven-clean.

Steps:

  1. Bind the maven-antrun-plugin:run goal to the pre-clean phase of mvn clean. See how to do this here

  2. See how to use the antrun plugin to run an external batch file in Windows here : sblundy's answer to "Starting external process". Let's call this file unlock_handles.bat

  3. Use the Sysinternals handle utility download link in the pre_clean.bat to a) stop the Tomcat server and b) unlock the .jar file. handle -c and handle -p would be useful here.

Whew! That's a bit of work, but it will reliably automate the process for you so that you do need to do it manually yourself each time!

OK, here's a rough, proof-of-concept version of unlock_handles.bat for you to try out:

REM "Use handle.exe to figure out the process id and handle ids, parse the output, then close the handle (again using handle.exe)"

cd "C:\Users\Nikolay_Tkachev\workspace\HHSystem\UI\target"
"c:/Program Files/Process Explorer/handle.exe" -p java.exe "C:\Users\Nikolay_Tkachev\workspace\HHSystem\UI\target" > handles.txt

@echo "O====== Going to unlock all the below file handles! =======O"
FOR /F "tokens=1-26 delims=: " %a in (handles.txt) DO @echo %h
FOR /F "tokens=1-26 delims=: " %a in (handles.txt) DO handle -p %c -c %f -y

Of course, you have to change the path to Sysinternals' handle.exe before giving this a try.

Solution 10 - Java

If all steps (in existing answers) dont work , Just close eclipse and again open eclipse .

Solution 11 - Java

For linux users: possible solution.

Build error due to "Failed to delete < any-file-or-folder >" will occur if there is by chance of only delete access provided to root user rather to normal-user.

Fix : type ll command to list file that cannot be deleted, if the file is given root access, change to normal user by :

> sudo chown -R user-name:user-name filename

Later try for maven clean and build.

Solution 12 - Java

solved by deleting the target folder manually.

Solution 13 - Java

I had similar issue. Earlier I was using Maven 3 to build the project. After switching to maven 2 , I had the above error.

Solved it by switching to Maven 3.

Solution 14 - Java

Maven complains if you do not have admin permissions on the target folder.Check if you have admin right to delete that folder.

enter image description here

Solution 15 - Java

I solved mine by doing:

  • mvn clean
  • mvn install
  • mvn clean install

For some reasons it worked for me . Good luck !!

Solution 16 - Java

If you lock org.ow2.util.asm-asm-tree-3.1.jar and start eclipse, the logging shows who was unable to lock the file. The same codeline who cant lock the file will not release the lock.

Solution 17 - Java

In pre-clean phase I execute with Maven Unlocker program. This program unlock all files and directory for anyone program.

I execute this with maven-antrun-plugin and only in windows systems

<profile>
  <activation>
    <os>
      <family>windows</family>
    </os>
  </activation>
  <build>
    <plugins>
      <plugin>
        <artifactId>maven-antrun-plugin</artifactId>
        <version>1.8</version>
        <executions>
          <execution>
            <phase>pre-clean</phase>
            <configuration>
              <tasks>
                <exec dir="${project.build.directory}" executable="cmd" failonerror="false">
                  <arg value="Unlocker.exe" />
                  <arg value="/S" />
                </exec>
              </tasks>
            </configuration>
            <goals>
              <goal>run</goal>
            </goals>
          </execution>
        </executions>
      </plugin>
    </plugins>
  </build>
</profile>

Solution 18 - Java

Please close all the browser tab. And next time when you try to upload war from another place except target folder.

Solution 19 - Java

If you run into this error in an IDE like Eclipse or IntelliJ, you may have one or more debug windows open and paused on a break-point. Terminate them.

Solution 20 - Java

The reason for this error is, the file which maven is trying to delete is being used by some process. One example of such process is Eclipse or any other IDE is doing validation on same project.

Please make sure that no validation running from eclipse or in any other IDE where project is open.

Solution 21 - Java

  1. I closed Git Bash (might be another terminal you are working on). It stops the process
  2. Delete ...0.0.1-SNAPSHOT.jar
  3. mvn clean install (or other start your project command; we have .sh)

Solution 22 - Java

> If you have a process running that using the packaged app deployed like an ftp or ssh session - it could prevent the resource being deleted or moved:

so identify the open port which is using the war or jar, close it - then restart

> sftp - ssh port : 22 > > ssh port : depend on config

Solution 23 - Java

for me

mvn install
mvn clean install

worked..
