Ant script: Have <exec> tag dump out entire command line
提问by opike
I have an ant build script with a fairly complex <exec>command with lots of <arg>tags that I'm trying to troubleshoot. I was wondering if it is possible to view the entire command line after ant has constructed it; either in the eclipse debugger or maybe by dumping it to a file.
我有一个 ant 构建脚本，其中包含一个相当复杂的<exec>命令，其中包含许多<arg>我正在尝试排除故障的标签。我想知道是否可以在 ant 构建后查看整个命令行；无论是在 eclipse 调试器中，还是通过将其转储到文件中。
Here's what I'm dealing with:
这是我正在处理的：

ant -v usually does the trick but you may find you have a lot of output to look through.
ant -v 通常可以解决问题，但您可能会发现有很多输出要查看。

What about some good old echoing via:
一些好的旧回声怎么样：
<echoxml>
<exec executable="..." failonerror="true" >
<arg value="..."/>
<arg value="..."/>
...
</exec>
</echoxml>
for testing your stuff (attribute values, properties resolved .. etc.) before activating the real thing !?
That's what I use frequently, because ant -verbose | debugis too chatty when I need to check only specific parts. Afterwards simply delete or comment the echoxmltags.
在激活真实的东西之前测试你的东西（属性值，属性解析......等）！？
这就是我经常使用的，因为ant -verbose | debug当我只需要检查特定部分时太健谈了。之后只需删除或评论echoxml标签。
For echoxmlyou need Ant >= 1.7
对于echoxml，您需要 Ant >= 1.7

Try using the log4j ANT listener. It can be configured to zero in on the Exec task output.
尝试使用log4j ANT 侦听器。它可以配置为在 Exec 任务输出中归零。
Example
例子
Project files
项目文件
$ tree
.
|-- build.xml
`-- lib
|-- log4j-1.2.16.jar
`-- log4j.properties
1 directory, 3 files
build.xml
构建文件
<project name="name" default="run">
<target name="run">
<exec executable="echo">
<arg line="hello world"/>
</exec>
</target>
</project>
log4j.properties
log4j.properties
log4j.rootLogger=ERROR, LogFile
log4j.logger.org.apache.tools.ant.taskdefs.ExecTask=DEBUG
log4j.appender.LogFile=org.apache.log4j.FileAppender
log4j.appender.LogFile.layout=org.apache.log4j.PatternLayout
log4j.appender.LogFile.layout.ConversionPattern=[%6r] %8c{1} : %m%n
log4j.appender.LogFile.file=build.log
Running the build
运行构建
Need to specify the listener and the directory containing the log4j dependencies:
需要指定监听器和包含log4j依赖的目录：
ant -listener org.apache.tools.ant.listener.Log4jListener -lib lib
Producing the following output in the build.logfile
在build.log文件中产生以下输出
$ cat build.log
[ 0] ExecTask : Current OS is Linux
[ 14] ExecTask : Executing 'echo' with arguments:
'hello'
'world'
The ' characters around the executable and arguments are
not part of the command.
[ 20] ExecTask : hello world
