build failed

[Valeria Lucchesi]

Hi! 

I'm trying to run some test from UnnecessaryTypeArgumentTest but i'm getting build errors. 

First i cloned the repo and then i did mvn package and everything worked as expected but when i want to run the tests from Intellij i''m getting a lot of errors. For example i got: 

class UnnecessaryLambdaParen is public, should be declared in a file named UnnecessaryLambdaParen.java

i'm using mvn 3.8.2 and Java version: 11.0.2

Do you know what could be happening?

Thanks in advance,

Vale

I mainly use IntelliJ to develop Error Prone, and I have exclusions defined for the 'testdata' directories to prevent it from trying to compile them:

$ find . -name '*.iml' | xargs grep testdata

./core/error_prone_core.iml:      <excludeFolder url="file://$MODULE_DIR$/src/test/java/com/google/errorprone/bugpatterns/android/testdata" />
./core/error_prone_core.iml:      <excludeFolder url="file://$MODULE_DIR$/src/test/java/com/google/errorprone/bugpatterns/flogger/testdata" />
./core/error_prone_core.iml:      <excludeFolder url="file://$MODULE_DIR$/src/test/java/com/google/errorprone/bugpatterns/inject/testdata" />
./core/error_prone_core.iml:      <excludeFolder url="file://$MODULE_DIR$/src/test/java/com/google/errorprone/bugpatterns/testdata" />
./core/error_prone_core.iml:      <excludeFolder url="file://$MODULE_DIR$/src/test/java/com/google/errorprone/refaster/testdata" />
./core/error_prone_core.iml:      <excludeFolder url="file://$MODULE_DIR$/src/test/java/com/google/errorprone/suppress/testdata" />

Possibly we should be checking those .iml files into version control so they're shared.
