DevOps - Maven: org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal org.apache.maven.plugins:maven-war-plugin:2.6:war

I'm configuring my maven project on DevOps, but I receive an assembling WAR error.

I've uploaded my project on the DevOps Repository and created a pipeline. My pipeline is composed by the following job:

• Download secure file
• Maven pom.xml
  • Maven POM file: eq/pom.xml
  • Goal(s): clean package install
  • Options: -X -s $(Agent.TempDirectory)/settings_cqm.xml
  • Advanced - JDK version/architecture: JDK 7/x64
• Copy ear
• Copy shared-lib
• Publish Artifact

Here is my eq/pom.xml file

I've already tried different configuration. Here some of them:

• To change the JDK version in DevOps setting it with the Default value.
• To eliminate the source and the target tag in the pom file and setting the JDK version in DevOps with JDK 7 value
• To add <failOnMissingWebXml>false</failOnMissingWebXml> line in the pom file

I'm stuck with this error and I don't have any other idea.

I solved the problem!

I have changed the tag <targetPath>WEB-INF/classes/</targetPath> to <targetPath>WEB-INF\classes\</targetPath>.
