ant - subant失败错误的微妙之处

Question

我有在所有子目录中启动发布版本的 ant 代码:

<target name="all-release" >
    <subant target="sub-release" failonerror="true">
        <fileset dir="." includes="*/build.xml" />
    </subant>
</target>

如所写，如果任何单个构建失败，则 all-release 将快速失败(以后的构建都不会成功。如果我切换 failonerror="false"，则 all-release 将一直成功。事实证明，所有子-builds 是独立的，所以我真正想要的是:

运行所有子发布构建，然后如果一个或多个子发布失败，则所有发布失败(理想情况下，带有关于哪些构建失败的错误消息)。

有任何想法吗？

建议您查看 ant-contrib 中可用的扩展任务。

'for' 任务可能可以根据您的要求进行调整。

您的“全部发布”目标和 ant-contrib taskdef 可能如下所示:

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

<target name="all-release">
    <for keepgoing="true" param="file">
        <path>
            <fileset dir="." includes="*/build.xml" />
        </path>
        <sequential>
            <ant antfile="@{file}" target="sub-release" />
        </sequential>
    </for>
</target>

使用其他一些 ant-contrib 功能可能会获得失败列表。

来自上面 build.xml 的示例日志:

$ ant all-release
Buildfile: build.xml

all-release:
     [echo] /work/Scratch/dir1/build.xml

sub-release:
     [echo] dir1
     [echo] /work/Scratch/dir2/build.xml

sub-release:
     [echo] dir2
      [for] /work/Scratch/dir2/build.xml: The following error occurred while executing this line:
      [for] /work/Scratch/build.xml:17: The following error occurred while executing this line:
      [for] /work/Scratch/dir2/build.xml:6: dir2 failed
     [echo] /work/Scratch/dir3/build.xml

sub-release:
     [echo] dir3

BUILD FAILED
/work/Scratch/build.xml:11: Keepgoing execution: 1 of 3 iterations failed.
