ANT build does not fail on errors [message #235550]

Hi;

I joined a project recently which uses Eclispe for Java development.
Working on that project i found a strange problem running the build files
- it allways completes _succesfull_ regardless of compilation errors. The
build.xml contains NO failonerror="false" anywere. I run the scripts with
the runs_as (ant build) Option.

I never saw such a strange behaviour using ant directly - and indeed
running the build with a external ant (1.7.0) results in the correct
behaviour (fails if javac encounters errors). Any idea whats wrong or how
to get it to behave the right way

PS This issue was found in 3.2 and 3.3 running on xpee

thx in advance;

Seems strange to me as well.
The Ant bundled within Eclipse is an unmodified distribution of the Apache
Ant release 1.7.0... we just launch differently.
Can you boil this down to a self contained example that you could open a bug
report with for further investigation?

Thanks

Hi;

I tried to reproduce that error but with no success yet. I have no idea
what in the structire of that files triggers that error. If i get any
further with that i send a bug report.

Hi;

I could reproduce the error with destdir="bin" in a javac task. For what
ever
reason those jerks didnt follow the usual convention (="classes") - but to
be honest i really dont know why the name matters.

The isolated example :

<?xml version="1.0" encoding="UTF-8"?>
<project name="Test" default="dist">
<property name="Appname" value="crap" />
<property file="build.properties"/>
<tstamp>
<format property="TODAY_VERSION" pattern="yyyy/MM/dd hh:mm"
locale="de,DE" />
</tstamp>


<path id="compile.classpath">
<fileset dir="lib" />
<fileset dir="props" />
</path>


<target name="copy" >
<echo> copy target (dummy) </echo>
<copy file="c:/temp/testa.txt" todir="c:/temp/testa" overwrite="true" />
</target>


<target name="compile" depends="copy" >
<echo> Compile target </echo>
<javac srcdir="src" destdir="bin" failonerror="true" >

</javac>
</target>


<target name="compress" depends="compile" >
<echo> JAR target </echo>
<jar destfile="Project.jar">
<fileset dir="classes" includes="**/*.class"/>
<manifest>
<attribute name="Main-Class" value="Testcase"/>
</manifest>
</jar>
</target>

<target name="dist" depends="compile" >
<echo>
Building the .jar file.
</echo>
<echo> Dist target </echo>
</target>
</project>

In this case even ant from commandline builds sucessfull - in a case with
a broken java source file. changing destdir to classes and it works like
expected.

Thanks.
But I am not sure there is as bug here.

the javac tasks does a simple time stamp comparison of the src and binaries.
If the src timestame is not newer than the binaries no compilation
occurs...you are up to date.
If eclipse is compiling the src to the bin directory (which it does by
default) your javac will be a no-op.
Are you sure you are actually compiling anything when things are
"successful". I would crank up your verbosity and ensure that something
really is being compiled.
