Ant-contrib 应该失败但不会

Question

我正在尝试使用一个包含两个目标的脚本来部署多个系统。当一个系统部署失败时，我想停止整个脚本并失败。

<target name="deploy_all">
    <for list="${systems}" param="system" delimiter="," parallel="false" threadCount="1" trim="true">
        <sequential>
            <antcall target="deploy_one_system">
                <param name="system" value="@{system}" />
            </antcall>
        </sequential>
    </for>
</target>

<target name="deploy_one_system">
    <trycatch property="error_system">
        <try>
            <!-- deployment -->
            <!-- Deep in other targets, there's <fail> -->
        </try>
        <catch>
            <echo>Error during deployment of ${system}:</echo>
            <echo>${error_system}</echo>
            <!-- print logs, errors, cleanup -->
            <if>
                <contains string="${stop_execution_on_fail}" substring="${system}" />
                <then>
                    <echo message="I should fail here!" />
                    <fail message="Error occured during deploying ${system}."/>
                </then>
            </if>
        </catch>
    </trycatch>
</target>

问题是条件被正确评估并且消息“我应该在这里失败！”被打印，但构建没有失败并继续部署下一个系统。

变量 ${stop_execution_on_fail} 被提供给脚本并包含应该使整个构建失败（而不是部署其余系统）的系统列表。

有时，在部署多个内存不足的系统后构建会失败。

17:07:03 deploy.xml:900:

我正在运行 Jenkins 1.642.1、JDK 1.8.0_74 和 Ant 1.9.2。

有什么想法吗？

编辑（基于 pczeus 的评论）：打印以下内容（不要介意时间戳，我从另一个版本中获取）：

10:12:56      [echo] Error during deployment of system1:
10:12:56      [echo] The following error occurred while executing this line:
10:12:56      [echo] deploy.xml:739: The following error occurred while executing this line:
10:12:56      [echo] deploy.xml:647: The following error occurred while executing this line:
10:12:56      [echo] deploy.xml:473: The following error occurred while executing this line:
10:12:56      [echo] dbmaintain.xml:229: Unable to perform db maintain task.

--- omitted ---

10:12:56      [echo] I should fail here!

如您所见，条件评估成功，因为消息 I should fail here! 被打印出来。

stop_execution_on_fail 变量包含以逗号分隔的失败系统列表：

system1,system2,system3

Answer 1

我相信你的问题是在你的

<contains string="${stop_execution_on_fail}" substring="${system}" />

您正在检查整个字符串stop_execution_on_fail 中与系统匹配的子字符串。但是，您的尝试：

<trycatch property="error_system">

正在 error_system 属性中设置错误消息，而您没有将其签入包含。

尝试将<contains> 更改为：

<contains string="${error_system}" substring="${system}" />

我使用Chad Nouis' 的建议追踪了错误并发现了以下内容：

• 首先，当我没有发布实际代码而只是摘录并替换了一些变量时，我很愚蠢。真丢脸！
• <for> 调用中的parallel 属性在deploy_all 目标中设置为真。在这种情况下，即使将 threadCount 设置为 1，Ant 也会使目标失败，但不会阻止 for 循环运行下一个循环（尽管我确信它应该这样做）。

谢谢Chad Nouis！
