Subject [jira] [Commented] (GROOVY-7166) Can't build Groovy project due to too long file name
Date Thu, 18 Aug 2016 17:32:21 GMT

    [ https://issues.apache.org/jira/browse/GROOVY-7166?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15426854#comment-15426854
] 

Stefán Freyr Stefánsson commented on GROOVY-7166:
-------------------------------------------------

There is quite some time since this was reported but in case anyone stumbles in here (as I
did) I'd like to add that this may have been due to ecryptfs. Groovyc seems to be generating
filenames that are too long for the 143 character max limitation of that.

For more info see: https://bugs.launchpad.net/ecryptfs/+bug/344878

I had this problem when trying to compile the IntelliJ IDEA community project. When I moved
the directory out of my (encrypted) home directory, I was able to compile it.

The problem here seems to be that groovyc is not querying the filesystem for the max filename
lenght. As mentioned in the above ecryptfs bug report, groovyc should be using the statfs()
syscall to query for the max filename length which will be correctly reported as 143 by ecryptfs
filesystems and should take actions accordingly if generated files exceed that limit.
