GWT 1.52 Compile error

[timmys]

Hi,

I'm trying to upgrade my GWT 1.4 project to 1.52. But I get this
strange exception when invoking the compiler. I can compile the exact
same code with 1.4 perfectly.
Has anyone seen this before?

[Isaac Truett]

You have a corrupted jar file in your classpath, possibly due to an
interrupted download.

Did you fix this? I'm getting the same error. The checksum however
matches.

My Solution for InvalidJarIndexException:
1. If you are including any jars built from GWT, they all need to be
compiled in the latest library as well
2. I had an old gwt-ext library in my libs folder, and when I deleted
it, all problems went away.

Hope that helps someone

You can try regenerating the jar index by running this command:

jar i some-jar-file.jar
