“The command line is too long” error in dexDebugTest build task

问题

I followed this link to set up test cases in Android Studio:

But if I try to run some tests in my project I get the following error:

**Execution failed for task ':common_lib_app:dexDebugTest'.**
> com.android.ide.common.internal.LoggedErrorException: Failed to run command:
    C:\Program Files (x86)\Android\android_studio\sdk\build-tools\19.1.0\dx.bat --dex --num-threads=4 --output D:\Android\android_studio\

update error:

The command line is too long.

 FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':commom_lib_app:dexDebugTest'.

I have multiple projects with a common library class (i.e ==common_lib_app).

Here is my build.gradle:

 androidTestCompile('junit:junit:4.11') {
  exclude group: 'org.hamcrest', module: 'hamcrest-library'
    }
    androidTestCompile 'org.hamcrest:hamcrest-library:1.3'
    androidTestCompile 'com.jayway.android.robotium:robotium-solo:5.2.1'
    androidTestCompile 'org.mockito:mockito-core:1.9.5'
    androidTestCompile 'com.google.dexmaker:dexmaker-mockito:1.0'
    androidTestCompile 'com.google.dexmaker:dexmaker:1.0'
    compile 'com.github.tony19:logback-android-core:1.1.1-2'
    compile 'com.github.tony19:logback-android-classic:1.1.1-2'
    compile 'com.nostra13.universalimageloader:universal-image-loader:1.9.2'
    compile 'com.squareup.okhttp:okhttp:1.5.4'
    compile 'de.greenrobot:eventbus:2.2.1'
    compile 'com.android.support:appcompat-v7:20.0.0'
    compile 'com.android.support:gridlayout-v7:20.0.0'
    compile 'com.android.support:support-v4:20.0.0'
    compile 'com.commonsware.cwac:endless:1.2.3'
    compile 'com.nhaarman.listviewanimations:library:2.6.0'
}

Can anyone help me to solve this problem?

This is bug https://code.google.com/p/android/issues/detail?id=75936 (Support new dx option: --input-list=) which has been fixed in later versions of Android Studio. I believe you're running an older version; a modern version wouldn't allow you to use Build Tools 19.1.0. Try updating Android Studio, following its instructions to update your build scripts to use the latest version of the Android Gradle plugin, and see if that solves your problem.
