Ant：根据目标调用深度缩进回显输出

Question

对于较大的 ant 构建结构和相当复杂的项目，我想根据目标调用深度缩进信息输出（回显），例如：

[echo] running build from project/build.xml
    [echo] running build from project/sub1/build.xml
    [echo] running build from project/sub2/build.xml
        [echo] running build from project/sub2/sub21/build.xml
        [echo] running build from project/sub2/sub22/build.xml
    [echo] running build from project/sub3/build.xml

BUILD SUCCESSFUL
Total time: x seconds

是否有这样的调整、记录属性或其他什么？ ...也许是 xslt/css 或事件监听器？

缩进不是重点，而是查看调用层次结构：避免搜索 build.xml 文件或在所有目标和宏定义中添加自己的 echo 函数。

见https://ant.apache.org/manual/listeners.html

XmlLogger 在那里似乎很有帮助，如果有点过于冗长 - 您可以通过一些脚本提取调用层次结构（也带有回声）：

ant -logger org.apache.tools.ant.XmlLogger 构建

Log4j 也取得了一些成功：

ant -listener org.apache.tools.ant.listener.Log4jListener -lib ..../logging-log4j-1.2.17/dist/lib/ -lib 。构建

为此，我使用上面第一个链接中的示例内容在当前目录中放置了一个 log4j.properties 文件。 这将生成一个包含以下内容的 build.log：

[     0]  Project : Build started.
[   908]  Taskdef : Could not load definitions from resource checkstyletask.properties. It could not be found.
[   995]   Target : Target "build" started.
[  4312]     Echo : com.ohmy: ivy.sorted.modules=thirdparty-plugins#com.sun.jaxb
[  4529]  Taskdef : Could not load definitions from resource checkstyletask.properties. It could not be found.
[  4588]   Target : Target "build_empty_unittests_jar_to_fulfill_dependencies" started.
[  4590]   Target : Target "build_empty_unittests_jar_to_fulfill_dependencies" finished.
[  4591]   Target : Target "build_nodeps" started.
[  4591]     Echo : Calling target 'build' for module com.sun.jaxb
[  4770]  Taskdef : Could not load definitions from resource checkstyletask.properties. It could not be found.
[  4846]   Target : Target "check_module_targets_file_exists" started.
[  4847]   Target : Target "check_module_targets_file_exists" finished.
[  4847]   Target : Target "check_module_target_exists" started.
[  4847]   Target : Target "check_module_target_exists" finished.

现在我只需将其导入小红宝石单线黑客以缩进它：

ruby -pe 'BEGIN {$i=0};$i-=1 if /finished\.$/;print " " * $i;$i+=1 if /started\.$/' build.log  

产生

 [   908]  Taskdef : Could not load definitions from resource checkstyletask.properties. It could not be found.
 [   995]   Target : Target "build" started.

当然这可以改进，但现在对我来说已经足够了:)
