Question

I got error message every time I changed my pom.xml in eclipse.

Build errors for myapp; org.apache.maven.lifecycle.LifecycleExecutionException: Failed to ex         


        

Answer 1

I had a similar issue; what you should try is performing a mvn install from the POM directory itself, any Maven install you do next in Eclipse itself will work as well afterwards.
