Eclipse: java.lang.NoClassDefFoundError: org/objectweb/asm/Opcodes

[Rakesh Patel]

I am running roboelectric test in eclipse. I updated roboelectic jar to use alpha-2 from 1.2 since I was facing issues testing fragments. 

I came across this exception while running with alpha-2:

Any idea what can be wrong here?

Thanks,

I have encountered the exact same problem!

[Pete]

The problem is one of dependencies.

I found that if I tracked-down and added a jar with the correct classes in, and then another... and then another... I still end-up with unresolved dependencies.

It'd be great if the instructions could be updated for those of us who use Eclipse, and don't use Maven...

[Pete]

All now sorted.

I found that I had go here to download the "all with dependencies" jar (click on the Artifact tab):
https://oss.sonatype.org/index.html#nexus-search;quick~robolectric
... the specific file was this:
/org/robolectric/robolectric/2.0-alpha-3-SNAPSHOT/robolectric-2.0-alpha-3-20130422.230702-53-jar-with-dependencies.jar


... and then get this (which was missing from the above file ...)
http://repo1.maven.org/maven2/org/easytesting/fest-util/1.1.6/fest-util-1.1.6.jar

... My basic test then worked! :)
