We run mach in the object directory, but it appears that the -C argument fouls the object directory discovery. This avoids that issue. garvank: apply this patch, build from the command line, and then build from the IDE?

:base:prepareObjDir Error running mach: ['build', 'mobile/android/base/gradle-targets'] If it is helpful, a successful run looks like this: :base:prepareObjDir 0:00.40 /opt/local/bin/gmake -C /Users/gkeeley/c/src2/obj-fennec -j8 -s backend.RecursiveMakeBackend 0:03.58 /opt/local/bin/gmake -C mobile/android/base -j8 -s gradle-targets 0:03.61 omni.ja

With this patch, starting from the command-line and building still works.

In AS, Project Settings > Compiler > Command-line options Added |--stacktrace --debug| Lots of output https://pastebin.mozilla.org/7292189

the paste bin is truncated, here is the full log

Nick you were right, the OBJDIR has no effect. Simply running AS from the command-line is enough.

I think this is no longer an issue. garvank, can you re-open if appropriate?

Correct, I have multiple build environments, configured by my shell, and the environment for Finder-level apps uses an environment that is for another project. Essentially this is a byproduct of my particular setup.
