Maven Classpath Variables on Eclipse

Posted on by

Eclipse needs to know the path to the local Maven repository. Therefore the classpath variable M2_REPO has to be set.

Execute the following command:

mvn -Declipse.workspace=<path-to-eclipse-workspace> eclipse:add-maven-repo

OR

You can also define a new classpath variable inside Eclipse. From the menu bar, select Window > Preferences. Select the Java > Build Path > Classpath Variables page.
Add the variable M2_REPO with path <path-to-your-user-folder>\.m2\repository.

Apache Shiro – Sample code error

Compiling the sample code in the Apache Shiro sample folder through Maven returned the following error:

[ERROR] Failed to execute goal org.codehaus.mojo:buildnumber-maven-plugin:1.0-beta-4:create (default) on project samples-quickstart: Cannot get the revision information from the scm repository :

Adding the following parameter

 <revisionOnScmFailure>unversioned</revisionOnScmFailure>

to the section of the buildnumber-maven-plugin (line 395/396) in the root pom.xml file solves the problem.
