Jenkins builds failure in Crashlytics tasks

Question

I am new to Jenkins and Build Servers in general. I am working on setting up an Android project on Jenkins, and the application uses Crashlytics. Using Gradle, I set my tasks to a “clean build”, but anytime I get into the Crashlytics task, I get this error:

java.lang.Error: Classloader conflict in your Gradle environment, please verify you are running the latest Android plugin. 

and

 Crashlytics data directory at /Users/Shared/Jenkins/Library/Caches/com.crashlytics could not be created. 

I tried setting my Gradle tasks to "-x crashlyticsGenerateResourecesAlpha" (this task, which does not work) to skip the task, but this also does not work.

I checked that I installed the latest Android tools, emulators, etc. The Android plugins I just downloaded are the Android Emulator plugin and the Gradle plugin (both are the latest versions). I use Git to complete my project. I run the emulator before building the project. I point to the android-sdk folder in the Jenkins directory. I also configured JDK 1.7, and this points to the JDK directory in my local field (I am running Jenkins locally).

Here are the build versions that I got when running gradle -v :

 ------------------------------------------------------------ Gradle 1.11 ------------------------------------------------------------ Groovy: 1.8.6 Ant: Apache Ant(TM) version 1.9.2 compiled on July 8 2013 Ivy: 2.2.0 JVM: 1.7.0_55 (Oracle Corporation 24.55-b03) OS: Mac OS X 10.9.2 x86_64 

Is there anything else that can cause this error? Is there a plugin for Crashlytics that I don't know about? Also, if there are any Jenkins debugging tips that I may not suspect of, let me know and I will clarify the question with what I find.

Answer 1

I had the same error because the directory /Users/Shared/Jenkins/Library does not exist. If you create this directory and /Users/Shared/Jenkins/Library/Caches , the crashlytics tasks should complete.

Answer 2

These are the final commands you need to execute:

 sudo mkdir -p /Users/Shared/Jenkins/Library/Caches/com.crashlytics sudo chown jenkins:jenkins /Users/Shared/Jenkins/Library -R 

Here is the relational debug log for this case:
