Subject RE: [DKIM:FAIL] Re: [E] Javac: Command-Line Argument Files
Date Tue, 07 Aug 2018 14:57:22 GMT
Hi,

Thanks, I think that is the way to go. I can get it to work though as the compiler does not
find the needed classes. I checked the generated jar it looks correct. The paths are all
Relative, is that OK ?

Compilation fails because it can't resolve many classes, follow a snipped of my build.xml.

<delete file="="${basedir}/out.jar" failonerror="false" />
		  <local name="mine-classpath" />
		  <manifestclasspath property="mine-classpath" jarfile="${basedir}" >
		    <classpath refid="@{classpathref}"/>
		  </manifestclasspath>
		  <jar destfile="${basedir}/out.jar">
		    <manifest>
		      <attribute name="Implementation-Title" value="${ant.project.name}" />
		      <attribute name="Class-Path" value="${mine-classpath}"/>
		    </manifest>
		  </jar>
	[..]                    
                    <javac srcdir="@{src}"
			   encoding="UTF-8"
			   source="@{sourceVersion}"
			   target="@{destinationVersion}"
			   debug="@{debug}"
			   verbose="@{verbose}"
			   debuglevel="@{debuglevel}"
			   fork="@{fork}"
			   memoryinitialsize="@{minHeap}"
			   memorymaximumsize="@{maxHeap}">
                        <exclude name="**/package-info.java"/>
                        <compilerarg value="-proc:only"/>
                        <compilerarg value="-processor"/>
                        <compilerarg value="com.querydsl.apt.hibernate.HibernateAnnotationProcessor"/>
                        <compilerarg value="-s"/>
                        <compilerarg value="@{gen}"/>
          
		<classpath path="${basedir}/out.jar" />
                    </javac>
