gradle build is not working in linux

Question

So my gradle build file is working in Windows fine and all tests are passing. Now I am trying to get all my tests to pass in linux as well.

The following is a link to the repo: https://github.com/quinnliu/WalnutiQ

I first install gradle with the following instructions:

unix> wget http://services.gradle.org/distributions/gradle-1.10-bin.zip
unix> sudo unzip -q gradle-1.10-bin.zip -d /usr/local/
unix> echo "export GRADLE_HOME=/usr/local/gradle-1.10" >> .profile
unix> echo "export PATH=$PATH:$GRADLE_HOME/bin" >> .profile

Then I navigate into the WalnutiQ folder after git cloning it.

After typing to the command line "gradle build --stacktrace" I get the following error:

[ubuntu@ip-172-31-25-10:~/Desktop/WalnutiQ]$gradle build --stacktrace                                                                 :compileJava UP-TO-DATE
:processResources UP-TO-DATE
:classes UP-TO-DATE
:jar UP-TO-DATE
:assemble UP-TO-DATE
:compileTestJava UP-TO-DATE
:processTestResources UP-TO-DATE
:testClasses UP-TO-DATE
:test

BUILD FAILED

Total time: 1 mins 7.262 secs

Answer 1

Could it be a permissions error? Try running as a super user (sudo) or installing gradle to somewhere within your complete control. Scanning through the source code, it would suggest its failing copy a file from gradle installation to the build directory of your project. So either the file is missing, or we are getting a permission issue.

Answer 2

I am getting the same error but the files are all being written successfully. I can see them after I run the build.
