Ant Program Terminate

I am working on some ant tool and following is the code block:

<trycatch>
    <try>
        <if>
            <equals arg1="${project.dir}" arg2=""/>
            <then>
                <fail/>
            </then>
        </if>
    </try>
    <catch>
        <echo>
            &#xa;Project directory not found at the location: ${project.dir}
            &#xa;Please set your valid project directory in ant configuration file located under path: build/config.properties
            &#xa;-----------------------------|- Program Terminated -|-----------------------------
        </echo>
    </catch>
</trycatch>

and I am also using ant.contrib.jar for if, else ...etc functions

I problem is when ant throw this error of "project dir not found" the ant program gets terminates that fine. but it shows me following error also after my error:

So How can i remove or control this BUILD FAIL error ?

Solution

  • I think you want to terminate the program in case of your <catch>, So you should add a <throw/> in the end.

    <?xml version="1.0" encoding="UTF-8"?>
<project name="test" default="test" basedir=".">
    <taskdef resource="net/sf/antcontrib/antcontrib.properties">
      <classpath>
        <pathelement location="/usr/share/java/ant-contrib-1.0b3.jar"/>
      </classpath>
    </taskdef>
    <target name="test">
        <trycatch>
            <try>
                <if>
                    <equals arg1="true" arg2="true"/>
                    <then>
                        <echo>HIT</echo>
                        <fail/>
                    </then>
                    <else>
                        <echo>NO HIT</echo>
                    </else>
                </if>
            </try>
            <catch>
                <echo>
                    &#xa;Project directory not found at the location: ${project.dir}
                    &#xa;Please set your valid project directory in ant configuration file located under path: build/config.properties
                    &#xa;-----------------------------|- Program Terminated -|-----------------------------
                </echo>
                <throw/>
            </catch>
        </trycatch>
    <echo>AFTER ALL</echo> <!-- this shall not be called -->
    </target>
</project>

    produces this result:

    test:
HIT


Project directory not found at the location: ${project.dir}

Please set your valid project directory in ant configuration file located under path: build/config.properties
