Maven and Ant Can't run Java - CreateProcess error=206, The filename or extension is too long -

when maven via antrun executes java code dreaded error=206, filename or extension long

<java classname="com.me.api" failonerror="true" fork="true" maxmemory="128m" output="${wsdlfile}.out">   <arg value="${classname}" />   <arg value="${name}" />   <arg value="${wsdlfile}" />   <classpath>     <path refid="maven.test.classpath" />   </classpath> 

extending answer provided @user4386022: can define (starting ant 1.8) macro can if have same problem in different places in build process (and cannot copy-paste same snippet everywhere because ant not allow re-defining properties, error saying "manifest.classpath" defined.)

<macrodef name="create-classpath-jar" description="create classpath jar, avoid getting error createprocess error=206, filename or extension long">     <attribute name="classpathjar"/>     <attribute name="classpathref"/>     <sequential>         <!-- turn classpath property formatted inclusion in manifest.mf file -->         <local name="manifest.classpath.property"/>         <manifestclasspath property="manifest.classpath.property" jarfile="@{classpathjar}">             <classpath refid="@{classpathref}" />         </manifestclasspath>         <!-- create jar -->         <jar destfile="@{classpathjar}">             <manifest>                 <attribute name="class-path" value="${manifest.classpath.property}"/>             </manifest>                               </jar>     </sequential> </macrodef> 

to use macro in targets or tasks, use this:

<path id="myclasspath">    ......... </path> <create-classpath-jar classpathjar="classpath-compile.jar" classpathref="myclasspath" />
