FindBugs IDEA - ClassNotFoundException com.google.wireless.android.sdk.stats.IntellijIndexingStats

Question

FindBugs IDEA v1.0.1 Android Studio 3.4

I get this error when running FindBugs. I don't use com.google.wireless.android.sdk anywhere in the app.

Error:Internal error: (java.lang.ClassNotFoundException) com.google.wireless.android.sdk.stats.IntellijIndexingStats$Index java.lang.ClassNotFoundException: com.google.wireless.android.sdk.stats.IntellijIndexingStats$Index     at java.net.URLClassLoader.findClass(URLClassLoader.java:381)     at java.lang.ClassLoader.loadClass(ClassLoader.java:424)     at java.lang.ClassLoader.loadClass(ClassLoader.java:357)     at com.intellij.util.indexing.counters.IndexCounters.<clinit>(IndexCounters.java:34)     at com.intellij.util.indexing.impl.MapReduceIndex.<init>(MapReduceIndex.java:86)     at org.jetbrains.jps.backwardRefs.index.CompilerReferenceIndex$CompilerMapReduceIndex.<init>(CompilerReferenceIndex.java:214)     at org.jetbrains.jps.backwardRefs.index.CompilerReferenceIndex.<init>(CompilerReferenceIndex.java:73)     at org.jetbrains.jps.backwardRefs.JavaCompilerBackwardReferenceIndex.<init>(JavaCompilerBackwardReferenceIndex.java:12)     at org.jetbrains.jps.backwardRefs.JavaBackwardReferenceIndexWriter.initialize(JavaBackwardReferenceIndexWriter.java:74)     at org.jetbrains.jps.backwardRefs.JavaBackwardReferenceIndexBuilder.buildStarted(JavaBackwardReferenceIndexBuilder.java:40)     at org.jetbrains.jps.incremental.IncProjectBuilder.runBuild(IncProjectBuilder.java:358)     at org.jetbrains.jps.incremental.IncProjectBuilder.build(IncProjectBuilder.java:178)     at org.jetbrains.jps.cmdline.BuildRunner.runBuild(BuildRunner.java:138)     at org.jetbrains.jps.cmdline.BuildSession.runBuild(BuildSession.java:302)     at org.jetbrains.jps.cmdline.BuildSession.run(BuildSession.java:135)     at org.jetbrains.jps.cmdline.BuildMain$MyMessageHandler.lambda$channelRead0$0(BuildMain.java:229)     at org.jetbrains.jps.service.impl.SharedThreadPoolImpl.lambda$executeOnPooledThread$0(SharedThreadPoolImpl.java:42)     at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511)     at java.util.concurrent.FutureTask.run(FutureTask.java:266)     at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142)     at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617)     at java.lang.Thread.run(Thread.java:745) 

Answer 1

To Solve this problem in Android Studio go to:

File
-> Settings
-> Build, Execution, Deployment
-> Compiler -> Java Compiler

Change javac to eclipse, and apply.

Answer 2

For what it's worth i got this exact error by importing a project started with IntelliJ Pro and imported into Android Studio - deleting the .idea directory at the root of the project and re-importing the project with Android Studio cleared it.
