问题描述
我有一些code:
<exec executable="src/main/webapp/bin/webdriver.bat" failonerror="true" resultproperty="return.code">
<arg line="${ccc}/eeee--report-format JSON --report-file testResultserer/resultere-data/wwwww.json"/>
</exec> (1)

So, now I would like to exec command , when (1) are going fail.

推荐答案
您可以返回code的值设置属性,然后有条件地执行的财产的价值的其他命令:
You can set property with the value of the return code and then execute the other command conditionally on the property's value:
<project>
<exec executable="${cmd}" resultproperty="ret1"/>
<condition property="cmd1failed" value="true">
<not>
<equals arg1="0" arg2="${ret1}"/>
</not>
</condition>
<exec executable="echo" xmlns:if="ant:if" if:true="${cmd1failed}">
<arg value="${cmd} failed"/>
</exec>
<exec executable="echo" xmlns:unless="ant:unless" unless:true="${cmd1failed}">
<arg value="${cmd} didn't fail"/>
</exec>
</project>
例如
$ ant -f exec.xml -Dcmd=/bin/true
Buildfile: /tmp/exec.xml
[exec] /bin/true didn't fail
BUILD SUCCESSFUL
Total time: 0 seconds
$ ant -f exec.xml -Dcmd=/bin/false
Buildfile: /tmp/exec.xml
[exec] Result: 1
[exec] /bin/false failed
BUILD SUCCESSFUL
Total time: 0 seconds
本使用,如果/除非出台属性蚂蚁1.9.1。
This uses the if/unless attributes introduced with Ant 1.9.1.
如果您正在使用Ant的旧版本,你必须使用单独的目标,像
If you are using an older version of Ant, you'll have to use separate targets, something like
<project default="both">
<target name="cmd1">
<exec executable="${cmd}" resultproperty="ret1"/>
<condition property="cmd1failed" value="true">
<not>
<equals arg1="0" arg2="${ret1}"/>
</not>
</condition>
</target>
<target name="cmd1-fail" depends="cmd1" if="cmd1failed">
<exec executable="echo">
<arg value="${cmd} failed"/>
</exec>
</target>
<target name="cmd1-pass" depends="cmd1" unless="cmd1failed">
<exec executable="echo">
<arg value="${cmd} didn't fail"/>
</exec>
</target>
<target name="both" depends="cmd1-fail,cmd1-pass"/>
</project>
