Subject RE: why does an ant task not work!
Date Mon, 28 Oct 2002 08:25:49 GMT
Sorry for a mistake about the directory structure in the previous email!
 
But i don't think it is a problem with directory structure.
because abuild.xml 's components target
 (      <target name="components" depends="init">
           <!-- the following task won't work -->
           <ant dir="${b.home}/src" target="core"/>
       </target> 
)
will lead bbuild.xml's target core to running. 
The problem is when the build process gets the bbuild.xml's target compile,
the javac task tell me that it can't find some classes in the "castor.jar"
jarfile,
which i have defined in the task javac's classpath attribute and if i build
project b independently  with ant, it will work fine--it can find the
classes in the "castor.jar" jarfile.


components\a
components\a\src
components\a\src\abuild.xml

components\b
components\b\src
components\b\src\bbuild.xml
 
Regards

In abuild.xml:
   <ant dir="${b.home}/src" target="core"/>
but your directory structure is:
  |----b 
  | |---bbuild.xml
Where is src? Or the directory structure is below?: 
  ....../b/ 
           src/bbuild.xml

In general, the problem is related with directory structure.
Can you send most simplest environment which
includes directory structure as attachment.

  Running "java org.apache.tools.ant.Main -buildfile bbuild.xml" command
will be ok!
  Running "java org.apache.tools.ant.Main -buildfile abuild.xml" command
will fail if the the previous command hasn't been ran!

  --project a's abuild.xml
  <project name="a" default="core" basedir="."/>
       <target name="init">
          <property name="a.src" ../>

          ...
       </target>

       <target name="components" depends="init">
           <!-- the following task won't work -->
