JavaCC problems
uffe
I have discovered a problem with building JavaCC (https://
javacc.dev.java.net/ && http://eclipse-javacc.sourceforge.net/)
projects using headlesseclipse. I get NullPointerExceptions as you can
see in the log below.
First, my Eclipse environment:
Buckminster - Core 1.1.350.r10694
org.eclipse.buckminster.core.feature.feature.group
Buckminster - PDE support 1.1.360.r10713
org.eclipse.buckminster.pde.feature.feature.group
Eclipse Git Feature 0.4.9.200906240051
org.spearce.egit.feature.group
Eclipse SDK 3.6.0.I20090917-0100 org.eclipse.sdk.ide
HeadlessEclipse 1.1.7 com.ind.eclipse.headlesseclipse.feature.group
JavaCC Feature 1.5.16 sf.eclipse.javacc.feature.feature.group
PyDev for Eclipse 1.5.0.1251989166
org.python.pydev.feature.feature.group
Pydev Mylyn Integration 0.3.0
org.python.pydev.mylyn.feature.feature.group
QuickImage 1.0.3 nu.psnet.quickimage.feature.group
Operating system is Mac OS X, 10.6.2.
Gábor gave me the advice that I try to reproduce it with a minimal
project, and I think I succeeded so here it is. It's just a JavaCC
sample project, but for your convenience I uploaded it.
http://dl.dropbox.com/u/436382/javacctest.zip
Create a new workspace, import "existing projects into workspace" and
choose the test directory extracted from the zip file above. The
grammar/ subdirectory contains a JavaCC .jj file, which when compiled,
will generate some .java source files. Right click the .jj file and
choose "Compile with JavaCC". It builds.
Now try with headlesseclipse:
./eclipse -nosplash -data /Users/monkey/headlesseclipsetest/ -
application com.ind.eclipse.headlessworkspace.Application import clean
build
