mvn jetty:run throwing java.util.zip.ZipException: invalid entry size

Question

Im trying to run a pretty basic project (its basicly a wireframe with no functionality at all, just some maven dependencies) in jetty. To do so I'm using mvn jetty plugin:

mvn jetty:run

But im getting this exception just after the server begins to start-up:

[INFO] Starting jetty 7.4.0.v20110414 ...
2012-08-16 13:25:22.237:INFO::jetty-7.4.0.v20110414

java.util.zip.ZipException: invalid entry size (expected 3313 but got 2163 bytes)

This sound to me like a corrupt jar somewhere, but I'm not sure how to proceed, this is my first time working with jetty.

Any ideas?

Answer 1

The issue, as I suspected, was due a corrupt JAR file. The solution for me was to clear my local repository (deleteing the content of .m2/repository folder) and execute:

mvn clean install

After all dependencies are resolved, it ran like a charm.

You should also ensure that the application is in fact being compiled to the output folder (in my case a folder called war) before jetty is started.

Answer 2

I found the following: How to programmatically copy jar files

This article said:

It usually occurs when text file entries in the source jar file contain some non-ASCII characters such as ^I ^Z ^D ^C. Some common files are META-INF/COPYRIGHT.html, META-INF/LICENSE.txt, etc, probably because these files were created in a non-ASCII editor but saved as text files. Open them in vi or vim to see these offending characters.

Maybe this is the cause of the error.
