'File name too long' error when building Spring with Gradle

Question

I tried to build Spring from source using: ./gradlew install

It fails with:

/home/dk/.gradle/caches/1.12/scripts/build_68eiq5ktt9740a7l1bofab8a9a/ProjectScript/no_buildscript/classes/build_68eiq5ktt9740a7l1bofab8a9a$_run_closure27_closure138_closure139_closure140_closure141_closure142_closure143_closure144_closure146_closure147.class (File name too long)

This was reported earlier but should have been fixed in Gradle 0.9.1. However I still have this error with Gradle 1.12. I'm using Ubuntu 14.04 with an ext4 filesystem.

What's the recommend workaround for this?

Answer 1

It seems that this error occurs when using an encrypted home directory. I've set GRADLE_USER_HOME to an unencrypted directory and everything works fine.

Answer 2

The only solutions I'm aware of are to use a filesystem that can handle long filenames, or to ask the Spring folks to change their build script so that it doesn't use such deep nesting levels (10 seems way too much). In any case, this question should be brought to attention of Spring developers (e.g. in their JIRA). I'd be surprised if none of them used Ubuntu/ext4.
