Error in building Randoop

[Islam Elgendy]

Hi,

I'm trying to build the code for Randoop. I have cloned the project from GitHub, and the first instruction to build the project is: ./gradlew build manual

it keeps on building for almost 7 mins, and a lot of tests pass, then at 57%, specifically at (randoop.main.minimizer.MinimizerTests > testWithMulitpleTestCases), the build fails with an exception.

The exception details are as follows:

Attempt 1 failed:
    command: [.\gradlew, -q, printJunitJarPath]
    exit status: -559038737  (failure)
    standard output:

Any idea how to fix this?

It looks like you are using Windows.  I don't use that OS, but I just made commit 02471b86 that might solve your problem.  If not, could you provide a patch?

Hi Mike,

Thanks for your reply. 

I have pulled the latest update of the project. Unfortunately, the error is the same as before (Same exception). I'm not sure if it has to do with my OS (Windows 10).

Best,

Islam

Can you explain more about what do you mean by "provide a patch"?

[Michael Ernst]

To provide a patch means to make changes to the source code that correct a problem.  Good luck!

Mike
