Process fork failed - at org.testng.TestNGAntTask.executeAsForked(TestNGAntTask.java:824)

Hi All,

I am not sure what is the issue but my ant build script is getting
failed with below error :
My classpath is huge and I assume it is getting failed because of that
but how to solve this?

From past 6 hours I was working on this but couldn't solve, can you
please help me out?

C:\CR\uibuild.xml:76: Process fork failed.

This may be because your M2_REPO directory have so many jars and may exceeds the classpath size or something like that.

The same problem I faced and resolved by extracting relevant jars to some other location and given that path only.

I hope that would work for you.

Thanks

Hi Amit Singh Ji,
Your solution for the above problem worked for me, by removing unnecessary jar files and also shortening the classpath where the files are located.
Thank You.
