How to debug (better yet, fix :-) the failure of a javac task like
> serverGUI.jar:
> [javac] Compiling 37 source files to <a path/>
> [javac] javac: invalid target release: ${javac.target}
given that the same ant script works, with the same options set, under
eclipse? Details:
I have an ant script that builds two apps (a client and a server) and
runs them. I've been successfully running the script from eclipse
while developing the apps; to deploy I want to run from the
commandline. I'm required to checkout from an ssh-only CVS repository,
and my laptop runs winXP, so I've been running eclipse from a cygwin
bash shell running ssh-agent, then running the ant script from eclipse
with Run As>Ant Script etc.
I then tried to run the ant script directly from bash with a bash
script that sets up vars (ANT_HOME, which points to 1.6.5, is already
set in my environment) then calls ant:
> mkdir -p $BUILD_DIR
> pushd $BUILD_DIR
> cvs -d:ext:${CVS_ID}:${CVS_PATH} co $CVS_MODULE
> popd
> pushd $BUILD_DIR/$CS_MODULE
> ant runLocalSession
but I get the "javac: invalid target release" error above on the
compiles for both the server and client JARs. However my build.xml is
setting what appear to be reasonable values (which I am not
overriding)
> <project name="buildController" default="build.jars" basedir=".">
> <property name="basews" value="${ws}"/>
> <property name="baseos" value="${os}"/>
> <property name="basearch" value="${arch}"/>
> <property name="basenl" value="${nl}"/>
> <!-- Compiler settings. -->
> <property name="javacFailOnError" value="false"/>
> <property name="javacDebugInfo" value="on"/>
> <property name="javacDebug" value="true"/>
> <property name="javacVerbose" value="true"/>
> <property name="javacSource" value="1.3"/>
> <property name="javacTarget" value="1.2"/>
> <property name="compilerArg" value=""/>
> <path id="path_bootclasspath">
> <fileset dir="${java.home}/lib">
> <include name="*.jar"/>
> </fileset>
> </path>
> <property name="bootclasspath" refid="path_bootclasspath"/>
nor does Eclipse appear to be overriding them: when I inspect the
runconfig for the script I see, on the Properties tab,
javacSource 1.3
javacTarget 1.2
Some other things I tried, just to rule them out:
* not using cygwin. Running
> pushd %BUILD_DIR%
> cvs -d:ext:%CVS_ID%:%CS_PATH% co %CS_MODULE%
> popd
> pushd %BUILD_DIR%\%CS_MODULE%
> ant runLocalSession
from a cmd shell (after setting vars its way) draws the identical
error.
* using different Javas. I get the same failure whether my JAVA_HOME
points to 1.5.0_05 (which is the default Installed JRE in my
eclipse) or 1.4.2_06
What am I doing wrong? What else do I need to do to investigate?
Replies directly to me (as well as the newsgroup) are appreciated.
Feel free to forward, and TIA.

context:
* eclipse 3.2-M3
* Sun java 1.5.0_05
* ant-1.6.5
I'm trying to test a build process. The process is currently contained
in a project in my workspace, and I kick it off by running a target in
the project's build.xml. This works now (both within eclipse and from
the commandline), but I'd like to have tests to prevent regression. I
have created a JUnit class (CcbTestAAABuildTest) in the project, the
fixture of which I'd like to run the build as directly as possible,
e.g. by just invoking the target programmatically. I saw
http://help.eclipse.org/help31/index.jsp?topic=/org.eclipse. platform.doc.isv/guide/ant_running_buildfiles_programmatical ly.htm
aka
http://127.0.0.1:60920/help/topic/org.eclipse.platform.doc.i sv/guide/ant_running_buildfiles_programmatically.htm
so am attempting to use AntRunner with code like
> /**
> * Tests are wrapped so that the long-running setUp() (i.e. running
> * the build) only runs once.
> */
> public static Test suite() {
> TestSuite suite = new TestSuite();

But when I run the class via Run>JUnit, AntRunner fails with console
like

org.eclipse.ant.core.AntRunner.getClassLoader(504) is

Is there something I can/must do to make this work? or is there a
better way to test the build process?
Please reply directly to me (as well as the newsgroup) if possible,
feel free to forward, and TIA.

Run it as a JUnit Plugin test.
You need the plugin framework etc so that the AntCorePlugin exists
