Ant build.xml cannot find symbol in included .jar

Question

I am migrating multiple projects from a purely desktop Eclipse dev & build to a buildserver (Jenkins-CI) environment. For this project, I can run the build.xml -> Run As -> Ant build successfully under Eclipse, but it fails when running on the buildserver. I feel I'm missing something elementary, but I've spent far to many hours looking at this. Any ideas what is missing?

<path id="lib-classpath">
    <!-- create a path to the lib files used in the javac compilation -->
    <fileset dir="${lib.dir}">
        <include name="*.jar"/>
    </fileset>
</path>

<target name="init">
    <mkdir dir="${bin.dir}"/>
    <mkdir dir="${lib.dir}"/>
</target>

<target name="check-DatabaseUtil">
    <property name="DatabaseUtil.dir" value="../../DatabaseUtil/workspace" />
    <property name="DatabaseUtil.jar" value="DatabaseUtil.jar" />
    <echo message="checking for ${DatabaseUtil.dir}/${DatabaseUtil.jar}..."/>
    <available file="${DatabaseUtil.dir}/${DatabaseUtil.jar}" property="DatabaseUtil.present"/>
</target>

<target name="do-if-DatabaseUtil" depends="check-DatabaseUtil" if="DatabaseUtil.present">
    <echo message="copy ${DatabaseUtil.dir}/${DatabaseUtil.jar} into directory ${lib.dir} ..."/>
    <copy file="${DatabaseUtil.dir}/${DatabaseUtil.jar}" todir="${lib.dir}" />
</target>

<target name="compile" depends="init, do-if-DatabaseUtil">
    <echo message="compile from directory ${source.dir} into directory ${bin.dir} ..." />
    <javac srcdir="${source.dir}" destdir="${bin.dir}">
        <classpath refid="lib-classpath"/>
    </javac>
</target>

<target name="jar" depends="compile">
    <property name="jar.name" value="${ant.project.name}.jar"/>
    <echo message="create file ${jar.name} ..." />
    <jar basedir="${bin.dir}" jarfile="${jar.name}">
        <fileset dir="${lib.dir}">
            <!-- include the library .jars into the file project .jar file -->
            <include name="*.jar"/>
        </fileset>
    </jar>
    <echo message="Done" />
</target>

when I run the build on the buildserver using Jenkins, it apparently fails to find the DatabaseUtil.jar that is present in the lib dir. Here's the recorded console output:

Answer 1

尝试<fileset dir="${lib.dir}"> <include name="**/*.jar"/> </fileset>

Answer 2

Make it point to your exact jar files directory where jars are present

<path id="classpath">
            <fileset dir="${main.jar}" includes="**/*.jar"/>
        <!-- <pathelement location="${src.dir}" />-->
    </path>

----in my case jar files present in ----
<property name="main.jar"     value="jar"/>
