Eclipse/Ant/javac and fork=true [message #196596]

Tue, 17 February 2004 17:42

OS:Windows XP
Eclipse: 3.0M6

I have an ant build.xml file with the following target:

<target name="build" depends="init">

<mkdir dir="${build.dest}" />


<javac fork="yes" classpath="${classpath}"
srcdir="${build.src}"
destdir="${build.dest}"
debug="${debug}"
optimize="${optimize}"
excludes="**/*~"/>
</target>

If I run ant (v 1.6) from the command line the above javac task is
processed just fine. However, if I run ant from inside Eclipse the
above target fails with the following error:

[javac] javac: invalid flag: C:\Documents

If I remove the fork="yes" from the above the build runs as expected.
I'm looking for an *easy* way to deal with this. For various reasons
my team wants to keep the fork=yes and I would like to be able to have
my Eclipse workspaces located anywhere on the file system and not
require paths that do not contain spaces (a rediculous restriction in
2004).

I'm hoping there is something obvious I'm missing in configuration and
was hoping someone out there could help, or is this a bug in Eclipse?

This could be a bug in Eclipse...I will check shortly.
How are you running the Ant build within Eclipse; in the same VM as Eclipse
or in a separate VM? Have you tried both?
Have you tried running from the commandline in the exact same location that
your workspace is in (to remove the possibility of an Ant bug)?

Always put quotes around directories that contain spaces. This will allow
the ant script to work inside and outside of eclipse (with or without
forking).

Assuming you're talking about the "Run Ant..."/JRE tab I just tried
both options of "Run in the same JRE as the workspace" and "Alternate
JRE" (no additional arguments) with the same outcome. (FWIW I'm
running 1.4.2.01 SDK).

CD'ing to my workspace/project directory and running ant on the
commandline yeilds a successful build of the project.

I thought I had, the classpath is set to "${classpath}" how many do I
need? :)

If you could take the time to log a bug report against Platform Ant I can
take a look.
Please include all the details like a sample buildfile, a sample classpath
etc.

Thanks
