subant failonerror微妙之处 [英] subant failonerror subtleties

问题描述

我有蚂蚁code揭开序幕发布版本中所有子目录：

I have ant code that kicks off a release build in all subdirectories:

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

由于写的，如果有个别构建失败，所有的释放将失败快（没有后来的构建将取得成功。如果我切换failonerror =false时，所有的释放将接替所有的时间。事实证明，所有的子版本是独立的，所以我真正想要的是：

As written, if any individual build fails, all-release will fail fast (none of the later builds will succeed. If I switch failonerror="false", the all-release will succeed all the time. It turns out that all the sub-builds are independent, so what I really want is:

运行所有子发布版本，然后都释放失败之后，如果一个或多个子版本失败（最好有哪些未能建立一个很好的错误消息）。

run all sub-release builds, and then have all-release fail afterwards if one or more sub-releases failed (ideally with a nice error message about which builds failed).

任何想法？

推荐答案

建议你看看扩展可用在蚂蚁的contrib 任务。

Suggest you look at the extensions available in the ant-contrib tasks.

在'为'任务大概可以调整，以满足您的要求。

The 'for' task can probably be adapted to meet your requirements.

您全释的目标，与蚂蚁的contrib的taskdef可能是这样的：

Your 'all-release' target, with the ant-contrib taskdef might look like this:

<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>

使用其它一些蚂蚁的contrib特征有可能获得该列表的失败。

Using some other ant-contrib features it may be possible to get the list of fails.

示例日志从上面的build.xml：

Sample log from above build.xml:

$ 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.
