Ant构建失败但始终在Jenkins中执行目标

Question

[解决] - 没有从我系统上的默认位置拾取正确的ant contrib jar。必须在build xml中手动提供路径，如下所示：

    <taskdef resource="net/sf/antcontrib/antlib.xml">
        <classpath>
            <pathelement location="/usr/share/ant/lib/ant-contrib-1.0b3.jar"/>
        </classpath>
    </taskdef>
-------------------------------------------

问：我有一个python脚本，通过ant / Jenkins运行，如下所示：

<project name="prjName"> 
    <target name="preRun" description="do something">
    .... 
    </target>
    <target name="Run" description="Run the python script">
        <exec executable="python" failonerror="true">
           <arg value="${basedir}/run.py" />
           <arg value="something" />
        </exec>
    </target>
    <target name="other1" description="do something">
     ....
    </target>

    <target name="other2" description="do something">
     ....
    </target>

</project>

现在这个python脚本运行一个外部工具（web-inject产生一些结果文件）并继续扫描日志中的单词FAIL。一旦发现失败，它就会sys.exit("Error")

因此构建失败但我仍然想要执行目标 - other1。是否有可能通过try-catch？我这样做但是没有用

    <macrodef name="test-case">     
         <sequential> 
             <trycatch>
                <try>
                    <exec executable="python" failonerror="true">
                        <arg value="${basedir}/read.py" />
                    </exec>
                </try>
                <catch>
                    <echo>Investigate exceptions in the run!</echo>
                </catch>
                <finally>
                    <antcall target="other1" />
                </finally>
            </trycatch>
         </sequential>   
        </macrodef>    


<target name="other1" description="do something">
         ....
</target>
