Hi,
The apt ant task from org.eclipse.jdt.apt.core.build.JdtApt outputs
coarse-grained error messages, simple "(Found X errors)", like that
shown below:
compile:
[apt] Building workspace
[apt] Building: /TestAntBuild
[apt] Invoking Java Builder on /TestAntBuild.
[apt] Cleaning output folder for TestAntBuild
[apt] Build done
[apt] Building: /TestAntBuild
[apt] Invoking Java Builder on /TestAntBuild.
[apt] Preparing to build TestAntBuild
[apt] Cleaning output folder for TestAntBuild
[apt] Analyzing sources
[apt] Compiling TestAntBuild
[apt] (Found 1 error) Compiling TestAntBuild
[apt] (Found 1 error) Build done
Does anyone know if it is possible to get apt to show more details
somehow? I didn't see how from the javadocs, but maybe I'm missing
something. Detailed error output like that from the ant javac task
would be preferred:
compile:
[javac] Compiling 1 source file to
C:\Local\Java\workspace_test\TestAntBuild
[javac] ----------
[javac] 1. ERROR in
C:\Local\Java\workspace_test\TestAntBuild\Test.java (at line 12)
[javac] asdfasdfasdfasdf;
[javac] ^^^^^^^^^^^^^^^^
[javac] Syntax error, insert "AssignmentOperator Expression" to
complete Expression
[javac] ----------
[javac] 1 problem (1 error)
Thanks,
Bob

Thanks, Jeff, running ant with the -debug switch gives the error details
I was looking for. The apt task doesn't support debug="on".

Out of interest, are you using APT, that is, are you actually running
annotation processors? Or are you just using this as a way of getting a
headless Eclipse build?
Always interested in APT use cases...

No, we're not doing annotation processing. We're looking into using APT
for nightly headless builds that are aware of the
..settings/org.eclipse.jdt.core.prefs stored in subversion. These prefs
specify which warnings are to be treated as errors or ignored. We
decided on a prefs "gold standard" for our group and want to enforce
this on the nightly builds.
The JDT ant adapter doesn't have a parameter method like
prefFile="core.prefs" to make this easy. This case requires the
core.prefs file gets loaded by <property file="core.prefs"> and then
ant-contrib <for> be used to looping, a special string concat because
JDT adapter takes only one line of compilerargs for
line="-warn:+unusedLocal,unusedImport,..." etc. It is more complicated
than the apt task, but the apt task requires a workspace & eclipse home
be maintained for the nightly build machine.

This is sort of what Eclipse itself does; the nightly builds ignore the
per-project warning settings and instead use global settings. You might
want to look into how that's achieved. They've been doing it for much
longer than the APT task has existed :-)

Just to be clear here, the real enhancement request here should be for the
Platform to create an ant task to run Eclipse headless builds, so that you
don't have to use the APT task.
There may be some confusion between "apt" and "ant" going on. The APT task
was written specifically so as to permit people to run builds that required
Java 5 annotation processing: in the Sun JDK, apt is a separate command-line
tool, but in Eclipse there is no equivalent, so it's hard to create
command-line build scripts for projects if you have annotation processing
enabled.
Although APT is near and dear to my heart, I worry a little when I see it
taking on broad responsibilities like this :-) It's just a wee young
thing...
