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 构建之后查看整个命令行；要么在 Eclipse 调试器中，要么将其转储到文件中。

这是我正在处理的问题：

            </exec>

这是我得到的错误：

ant -v 通常可以解决问题，但您可能会发现有很多输出需要查看。

一些好的旧回声怎么样：

<echoxml>
 <exec executable="..." failonerror="true" >
  <arg value="..."/>
  <arg value="..."/>
   ...
 </exec>
</echoxml>

在激活真实的东西之前测试你的东西（属性值，属性解析..等）！？
那是我经常使用的，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。

对于echoxml，您需要 Ant >= 1.7

尝试使用log4j ANT 侦听器。它可以在 Exec 任务输出上配置为零。

例子

项目文件

$ tree
.
|-- build.xml
`-- lib
    |-- log4j-1.2.16.jar
    `-- log4j.properties

1 directory, 3 files

构建.xml

<project name="name" default="run">

    <target name="run">
        <exec executable="echo">
            <arg line="hello world"/>
        </exec>
    </target>

</project>

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

运行构建

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

在build.log文件中生成以下输出

$ 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
