Ant Build Successful but neither jar file nor build folder created ?

[Prabhat Ranjan]

Hi,

I am building a project using only 1 file to test for Ant.

This is my code:

<project>

    <target name="clean">
        <delete dir="build"/>
    </target>

    <target name="compile">
        <mkdir dir="/build/classes"/>
        <javac srcdir="src" destdir="build/classes"/>
    </target>

    <target name="jar">
        <mkdir dir="build/jar"/>
        <jar destfile="build/jar/LogClass.jar" basedir="build/classes">
            <manifest>
                <attribute name="Main-Class" value="oata.HelloWorld"/>
            </manifest>
        </jar>
    </target>

    <target name="run">
        <java jar="build/jar/LogClass.jar" fork="true"/>
    </target>

</project>

But i don't see any output in the director or even directory created.

Here is successful build output:

Buildfile: C:\Workspace_log4j\testLog4j\build.xml
BUILD SUCCESSFUL
Total time: 63 milliseconds

Also i am attaching the directory structure of the Project.

What target are you running? I don't see any default target in your build file. Also the output you posted is just the last couple of lines. Please post the rest of the relevant output.

[Prabhat Ranjan]

Buildfile: C:\Workspace_log4j\testLog4j\build.xml
BUILD SUCCESSFUL
Total time: 78 milliseconds

This is the complete output here from console.

So, what target are you running? Maybe try running a target. Or setting a default target.

[Prabhat Ranjan]

I think i am using the defult target !

[David Newton]

Which is...?

[Prabhat Ranjan]

I don't know exacty and it could be the workspace_xyz and then the build folder.

[David Newton]

*Ant* target. What task do you think is running? Have you trying specifying one?

[Peter Johnson]

There is no default target in ant and you have not specified one in the <project> statement, so if you do not specify a target on the command line then ant will do nothing. And as it reported, is was successful at doing nothing.

<project name="test" default="dist" basedir=".">
    <description>
        simple example build file

  <!-- set global properties for this build -->
  <property name="src" location="src"/>
  <property name="build" location="build"/>
  <property name="dist"  location="dist"/>

  <target name="init">

    <tstamp/>

    <mkdir dir="${build}"/>
  </target>

  <target name="compile" depends="init"
        description="compile the source " >
    <!-- Compile the java code from ${src} into ${build} -->
    <javac srcdir="${src}" destdir="${build}"/>
  </target>

  <target name="dist" depends="compile"
        description="generate the distribution" >
    <!-- Create the distribution directory -->
    <mkdir dir="${dist}/lib"/>

    <!-- Put everything in ${build} into the MyProject-${DSTAMP}.jar file -->
    <jar jarfile="${dist}/lib/test-${DSTAMP}.jar" basedir="${build}"/>
  </target>

  <target name="clean"
        description="clean up" >
    <!-- Delete the ${build} and ${dist} directory trees -->
    <delete dir="${build}"/>
    <delete dir="${dist}"/>
  </target>
</project>

the above code is working.
