Last week I imported Beam with IntelliJ and everything worked.

That said, I tried to import the Eclipse project and that doesn't compile
anymore. I didn't have time to figure out what happened though.

I have a pull request https://github.com/apache/incubator-beam/pull/1094 that 
fixes the compile issues.  It has two LGTM’s, just needs someone to merge it.

With eclipse, you need to have all the needed m2e connectors.   Some of them 
(find bugs, check style) can be auto-detected and installed when beam is first 
imported.   The apt one doesn’t.   You need to go to the eclipse marketplace, 
install it, then configure it in the Eclipse properties to turn on the 
“experimental” m2e-apt processing.   Once you do that, a refresh of the maven 
projects should result in it building/compiling.

Running tests is another matter.   Since eclipse compiles everything in a 
module in one pass (instead of two like maven), one of the apt processors 
doesn’t know where to output files and always dumps the files in /classes 
instead of /test-classes.   Thus, any test that relies on a runner will likely 
fail as it results in the “test” versions of various services from core being 
picked up.  A simple:

rm sdks/java/core/target/classes/META-INF/services/*

From the command line will fix that.   That should also be documented on the 
IDE page until someone can figure out how to work around it.

Hi Christian,

IntelliJ doesn't need any special config (maybe the code style can be
documented or imported).

Anyway, agree to add such on website in the contribute directory. I
think it could be part of the contribution-guide as it's first setup step.

Hello all,

I am new to the beam community and currently start making myself
familiar with the code.  I quickly found the contribution guide and was
able to clone the code and build beam using maven.

The first obstacle I faced was getting the code build in eclipse. I
naively imported as existing maven projects but got lots of compile
errors. After talking to Dan Kulp we found that this is due to the apt
annotation processing for auto value types. Dan explained me how I need
to setup eclipse to make it work.

I still got 5 compile errors (Some bound mismatch at Read.bounded, and
one ambiguous method empty). These errors seem to be present for
everyone using eclipse and Dan works on it. So I think this is not a
permanent problem.

To make it easier for new people I would like to write a documentation
about the IDE setup. I can cover the eclipse part but I think intellij
should also be described.

I already started with it and placed it in /contribute/ide-setup. Does
that make sense?

I currently did not link to it from anywhere. I think it should be
linked in the contribute/index and in the Contribute menu.
