Deploying Maven project throws java.util.zip.ZipException: invalid LOC header (bad signature)

Question

I am getting the below exception when I run my mvn install. I have even deleted the local repository and ran again getting same exception.

Answer 1

The solution for me was to run mvn with -X:

$ mvn package -X

Then look backwards through the output until you see the failure and then keep going until you see the last jar file that mvn tried to process:

Look at the last jar before it failed and remove that from the local repository, i.e.

$ rm -rf /Users/snowch/.m2/repository/org/eclipse/jetty/jetty-server/9.2.15.v20160210/
