Hi all,
I have a perfectly running Eclipse 3.3 with DRools 4.0.4 and JDK 1.5.14.
The rules are compiled with a post build Ant task which uses Janino (need it
for Tomcat compatibility).
Now OUTSIDE Eclipse it seems I cannot use that Ant task to save my life :(
I tried switching from Janino to the default compiler, same thing. I always get
this infamous error:
BUILD FAILED

at com.my.app.rules.DroolsCompilerAntTaskStandalone.execute(

That "DroolsCompilerAntTaskStandalone" is my task using the default compiler
like this:
PackageBuilderConfiguration conf = new PackageBuilderConfiguration();
conf.setClassLoader( loader );
PackageBuilder builder = new PackageBuilder( conf );
If I use Janino like below the error is exactly the same...
PackageBuilderConfiguration pkgBuilderCfg = new
PackageBuilderConfiguration();
pkgBuilderCfg.setClassLoader( loader );
JavaDialectConfiguration javaConf = (JavaDialectConfiguration)
pkgBuilderCfg.getDialectConfiguration( "java" );
javaConf.setCompiler( JavaDialectConfiguration.JANINO );
PackageBuilder builder = new PackageBuilder( pkgBuilderCfg );
Again, in Eclipse all is working fine. I checked Ant's classpath, here it is:
E:\apache-ant-1.7.0\bin\..\lib\ant-launcher.jar
E:\apache-ant-1.7.0\lib\*.jar
C:\Program Files\Java\jdk1.5.0_14\lib\tools.jar
Here is how I provide a classpath:
<taskdef name="rulescompiler" classname="com.my.app.rules.
DroolsCompilerAntTaskStandalone" classpathref="droolsutils.classpath" />
<target depends="newfilesarethere" name="build" unless="rulesCompile.
notRequired">
<rulescompiler srcdir="${THIS_PROJ}/src/com/my/app/rules"
tofile="${THIS_PROJ}/build/classes/com/my/app/rules/
packaged.rules"
classpathref="droolsutils.classpath" >
<include name="*.drl" />
</rulescompiler>
</target>
The classpath I provide contains pretty much all libraries I use normally in
the project, but I tried even to add ALL jar's from the Eclipse 3.3 install
directory (that would include all DRools 4.0.4 libraries, with antlr and
whatnot)
I tried also with DRools 4.0.7, same behaviour...
What does that mean and where is it coming from? Could it have issues with the
tools.jar from Java 1.5.0_14?
Thank you for any input,
M
