Deploying Maven project throws java.util.zip.ZipEx

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

most of the time this happens because of the corrupt zars updating the maven central repository url in pom.xml file solved my problem you can use this url https://repo.maven.apache.org/maven2/ but before that delete the files in .m2 directory hope this helps

Answer 2

We can force the checksum validation in maven with at least two options:

1.Adding the --strict-checksums to our maven command.

2.Adding the following configuration to our maven settings file:

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0
                          https://maven.apache.org/xsd/settings-1.0.0.xsd">

Answer 3

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/

Answer 4

This answer is not for DevOps/ system admin guys, but for them who are using IDE like eclipse and facing invalid LOC header (bad signature) issue.

You can force update the maven dependencies, as follows:

Answer 5

Beyond removing .m2/repository, remove application from server, run server (without applications), stop it and add application again. Now it is supposed to work. For some reason just cleaning up server folders from interface doesn't have the same effect.
