回应ant文件集到屏幕进行调试

Question

我有这个:

    <ivy:buildlist reference="build-path">
        <fileset dir="${root.dir}">
            <include name="*/build.xml" />
            <include name="controllers/*/build.xml" />
        </fileset>
    </ivy:buildlist>


    <subant buildpathref="build-path">
        <target name="jar.all" />
        <target name="publish-local" />
    </subant>

我想要回应"构建路径"参考中的所有内容(用于调试某些内容).

我试过了:

<echo>${build-path}</echo>

但它只是回应了确切的文字"$ {build-path}"

Answer 1

你可以使用记录的(诚​​实的,它在某处......)toString帮助:

<echo message="My build-path is ${toString:build-path}" />

Answer 2

要调试文件集中包含的文件,可以使用此示例,该示例以可读格式打印文件集的内容:

<?xml version="1.0" encoding="UTF-8"?>
<project name="de.foo.ant" basedir=".">

<!-- Print path manually -->
<target name="print-path-manually" description="" >
    <path id="example.path">
        <fileset dir="${ant.library.dir}"/>
    </path>

    <!-- Format path -->
    <pathconvert pathsep="${line.separator}|   |-- "             
        property="echo.path.compile"             
        refid="example.path">
    </pathconvert>
    <echo>${echo.path.compile}</echo>
</target>

</project>

输出是:

Buildfile: D:\Workspaces\IvyTutorial\de.foo.ant\prettyPrintPath.xml
print-path-manually:
 [echo] D:\Programme\eclipse-rcp-helios-SR1-win32\eclipse\plugins\org.apache.ant_1.7.1.v20100518-1145\lib\ant-antlr.jar

 [echo] |   |-- D:\Programme\eclipse-rcp-helios-SR1-win32\eclipse\plugins\org.apache.ant_1.7.1.v20100518-1145\lib\ant-apache-regexp.jar
 [echo] |   |-- D:\Programme\eclipse-rcp-helios-SR1-win32\eclipse\plugins\org.apache.ant_1.7.1.v20100518-1145\lib\ant-apache-resolver.jar

Answer 3

启用ant的调试日志记录:

$ ant -h
ant [options] [target [target2 [target3] ...]]
Options:
...
  -verbose, -v           be extra verbose
  -debug, -d             print debugging information

请注意,这将产生大量输出,因此最好将输出捕获到文件,然后在文本编辑器中查找文件集信息:

ant -debug compile > ant-out.txt
