Question

when I run java test file(single file) through eclipse by passing arguments

-DappRoot=ECM -DappName=ESW -Dapp.module=FNT -Dapp.env=LOC -DcloneNumber=1

test file executes without error, if I dont give arguments error occurs as Could not resolve placeholder ‘appRoot’.

I have junit target to generate report in html format.

<target name="junit" depends="init-junit">
        <junit printsummary="on" fork="yes" forkmode="perBatch" haltonfailure="false" failureproperty="junit.failure" showoutput="false">           
            <classpath>
                <path refid="CLASSPATH_JUNIT"/>             
            </classpath>            
            <batchtest fork="no"  todir="${TEST_BUILD_DIR}">
               <fileset dir="${COMP_TEST_SRC}">                           
                  <include name="**/*Test.java" />          
               </fileset>              
            </batchtest>
            <formatter type="xml" />
        </junit>        
        <junitreport todir="${JUNIT_REPORT}">
            <fileset dir="${TEST_BUILD_DIR}">
                <include name="TEST-*.xml" />           
            </fileset>       
            <report format="frames" todir="${JUNIT_REPORT}"/>       
        </junitreport>          
    </target>       

When I run above build script, getting following error: Could not resolve placeholder ‘appRoot’ where this has passed as an arguments.

I have passed parameter to build.xml through eclipse, this parameter passes to build.xml file but not passing to java files. How can I solve this?

EDIT:
tried with following parameter:

<junit printsummary="on" fork="yes" forkmode="perBatch" haltonfailure="false" failureproperty="junit.failure" showoutput="false">           
    <jvmarg value="-DappRoot=ECM" />
    <jvmarg value="-DappName=ESW" />
    <jvmarg value="-Dapp.module=FNT" />
    <jvmarg value="-Dapp.env=LOC" />
    <jvmarg value="-DcloneNumber=1" />
    <!--<sysproperty key="appRoot" value="${appRoot}"/>
    <sysproperty key="appName" value="${appName}"/>
    <sysproperty key="app.module" value="${app.module}"/>
    <sysproperty key="app.env" value="${app.env}"/>
    <sysproperty key="cloneNumber" value="${cloneNumber}"/>-->
    <classpath>
        <path refid="CLASSPATH_JUNIT"/>             
    </classpath>

with system paramter it works fine but takes very long time to execute. with jvmarg it doesnt work. same error with

 <jvmarg value="-DappRoot=${appRoot}" />

http://ant.apache.org/manual/Tasks/junit.html doesn’t define any restriction for sys and jvm args.

The documentation of the junit ant task shows it:

<junit fork="yes" ...>
    <jvmarg value="-DappRoot=ECM" />
</junit>

If the appRoot property is passed as a system property to ant, you may access it as an ant property:

<junit fork="yes" ...>
    <jvmarg value="-DappRoot=${appRoot}" />
</junit>
