java - Invalid LOC header(bad signature)

Question

I am getting this error during my Maven build.

Failed to execute goal org.apache.maven.plugins:maven-shade-plugin:2.4.3:shade (default) on project dl4j-examples: Error creating shaded jar: invalid LOC header (bad signature) -> [Help 1] [ERROR]

This is my pom.xml file.

I have tried to delete the jar file multiple times that does not seem to work.

Answer 1

I also faced same issue, Ben is correct, it's the case of corrupt jar file. Just go to .m2 repo folder and delete it from there and again build it (mvn clean install). It would resolve the issue.
