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（echo），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，而是要查看调用层次结构：避免在所有目标和宏定义中搜索build.xml文件或添加自己的echo函数。

请参阅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 - 你可以通过一些脚本来提取调用层次结构（也有echos）：

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

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的示例内容将log4j.properties文件放在当前目录中。这将生成一个build.log，其中包含以下内容：

[     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，我只是把它管成一个小红宝石的衬里黑客来缩进它：

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

产生

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

      [  5069]     Echo : Skipping 'ivy_retrieve' as everything is uptodate for com.sun.jaxb

当然这可以改进，但现在对我来说已经足够好了：）
