Philip Zeyliger commented on HADOOP-5658:
-----------------------------------------
Eclipse on OS X is definitely whinier than on Linux, but I've gotten this to
work on both. I'm running through it as I type this up:
# Turn off Build Automatically
# Make sure that Eclipse Preferences...Installed JREs contains "JVM 1.6"
# Make sure ANT_HOME is set in Classpath Variables in Eclipse settings.
# Checked out Hadoop using Subversive as a New Java Project; using Java 1.6;
output path is build/eclipse-classfiles
# {{patch -p0 < /tmp/HADOOP-5658-v3.patch}}
# {{ant eclipse-files}} (When doing this for myself, I typically do
compile-core-test at this point too, just to accelerate things later.)
# Right-click on project and hit refresh in Eclipse
# Right-click on project and hit Build Project in Eclipse
# Refresh again
# Build project again.
# Check Problems: no errors, just warnings. Good.
So, it worked pretty much for me. I haven't managed to avoid the refresh/build
twice problem, though I've gotten it to work better if I built
compile-core-test on the command line ahead of time.
What version of Eclipse are you running? I'm at 3.4.2 (M20090211-1700) (on OS
X). To figure out what's going on, we'll also have to compare our .classpath,
.externalToolBuilders/Hadoop_Ant_Builder.launch, and .project files. I'm
attaching mine as eclipse.zip, for comparison. Can you send a screenshot of
the error you're seeing?

> "problems". I've produced a small patch that fixes it.
