Vaadin Context Menu Add On Error for 3.0.0.beta, but works for 2.1.0

Question

I am using Vaadin 8 and want to add-on latest 3.0.0.beta1 vaadin-context-menu. The maven update and build works fine but Tomcat fails to start with

<dependency>
   <groupId>com.vaadin</groupId>
   <artifactId>vaadin-context-menu</artifactId>
   <version>3.0.0.beta1</version>
</dependency>

I am getting Error with Message "java.util.zip.ZipException: invalid LOC header (bad signature)"

However, I able to successfully implement Context Menu for version 2.1.0

   <dependency>
        <groupId>com.vaadin</groupId>
        <artifactId>vaadin-context-menu</artifactId>
        <version>2.1.0</version>
    </dependency>

The error indicates that the JAR is broken. There is a bug in Eclipse's maven that breaks JARs randomly. Just delete it from .m2 cache and let maven redownload it.

The bug is described here https://bugs.eclipse.org/bugs/show_bug.cgi?id=534228

There is another StackOverflow discussion about the corrupt JAR's here, with solution how to find them: Deploying Maven project throws java.util.zip.ZipException: invalid LOC header (bad signature)

find  /home/me/.m2/repository/ -name "*jar" | xargs -L 1 zip -T | grep error | grep invalid

Clearing the cache didnt work either, the compile widgetset fails. – SDS Aug 08 '18 at 22:20
@SDS Did you clear it from the invisible Maven cache or just the Eclipse cache? – Basil Bourque Aug 09 '18 at 05:31
