ANT 脚本中的条件任务执行

Conditional task execution in ANT Scripts

我的要求很简单,我有一个 ANT 任务,它在内部处理异常并且不抛出任何异常,而是向控制台抛出自定义消息 [这些不是异常]。下面显示了带有测试 "The workspace with the specified name does not exist".

的示例

我的要求是,如果除了 "Build Successful" 之外还有任何此类消息,我应该确保我的 ANT 脚本失败,这样它就不会再继续下去了。但我无法这样做,因为我不知道如何阅读写入控制台的自定义消息。

我尝试探索 'Record' 任务,但我没有成功,因为这个日志只写到控制台而不是文件(不知道为什么)。但即使它被写入文件,我也应该理想地读取文件的每一行以找出是否存在特定文本。

有没有一种简单的方法可以尝试从控制台读取之前执行过的内容?

<target name="build">
    <record name="test.txt" action="start" append="true" loglevel="verbose" />
    <echo>Welcome to Apache Ant! Building the project in Cordys Middleware</echo>
    <property environment="env"/>
    <property name="bop.install.dir" value="${env.CORDYS_HOME}"/>
    <exec executable="${bop.install.dir}/components/cws/scripts/linux/CWSPackage.sh" failonerror="true" resultproperty="output">        
        <env key="CLASSPATH" value="/opt/Cordys/Oracle_Jar/ojdbc6.jar"/>
        <arg value="${ORG_NAME}"/>
        <arg value="${WORKSPACE_NAME}"/>
        <arg value="${PROJECT_NAME}"/>      
    </exec>
    <echo>Finishing the build</echo>
    <record name="test.txt" action="stop"/>
    <echo>${output}</echo>
    <fail>Something wrong here.</fail> <!-- I want to throw this error conditionally -->
</target>

您要查找的是 exec 任务的 outputproperty 属性。

你可以这样做:

<exec executable="${my.executable}" outputproperty="exec.output">
    <arg value="${my.arg}" />
</exec>

<fail message="Invalid output from exec task">
    <condition>
        <contains string="${exec.output}" substring="The workspace with the specified string does not exist." />
    </condition>
</fail>

多个条件(允许布尔值的任何复杂程度):

<fail message="Invalid output from exec task">
    <condition>
        <and>
            <not>
                <contains string="${exec.output}" substring="SUCCESS" />
            </not>
            <or>
                <contains string="${exec.output}" substring="ERROR" />
                <contains string="${exec.output}" substring="FAILED" />
            <or>
        </and>
    </condition>
</fail>

正则表达式:

<fail message="Invalid output from exec task">
    <condition>
        <matches string="${exec.output}" pattern="The .* does not exist." />
    </condition>
</fail>
<!-- *  This is an ANT script to build the project in development environment.
        Steps involved in this are

<project name="Building Project" default="build">
    <property file="${PROJECT}" /> 
    <target name="build">
        <echo>Welcome to Apache Ant! Building the project in Cordys Middleware</echo>
        <property environment="env"/>
        <property name="bop.install.dir" value="${env.CORDYS_HOME}"/>

        <exec executable="${bop.install.dir}/components/cws/scripts/linux/CWSPackage.sh" outputproperty="exec.output">      
            <env key="CLASSPATH" value="/opt/Cordys/Oracle_Jar/ojdbc6.jar"/>
            <arg value="${ORG_NAME}"/>
            <arg value="${WORKSPACE_NAME}"/>
            <arg value="${PROJECT_NAME}"/>      
        </exec>
        <fail message="Build not successful for the project ${PROJECT_NAME}">
            <condition>
                <not>
                    <contains string="${exec.output}" substring="Operation  completed successful" />
                </not>
            </condition>
        </fail>

    </target>
</project>

在使用了这么多的跟踪和错误方法之后,这对我有用。 谢谢奥斯汀。即使这是正在工作的 ANT,我也只会接受你的回答,因为这是你所说内容的修改版本:)
