Question

我正在尝试为我的JBoss AS 7项目制作一个Ant构建文件。构建文件应该将我的项目构建到EAR中。我得到了以下错误，所以我认为类路径被忽略了（如果我错了请纠正我。）

17 errors
C:\workspace\LearningAS7\GrahamsProj\build-handmade.xml:21: Compile failed; see the compiler error output for details.
BUILD FAILED (total time: 0 seconds)

所以现在我的构建文件看起来像这样：http://pastebin.com/NZWmQEjN（在这里发布的时间太长了）。如你所见，我放入了一个类路径部分。但现在我收到了这个错误：

C:\workspace\LearningAS7\GrahamsProj\build-handmade.xml:11: Problem: failed to create task or type classpath
Cause: The name is undefined.
Action: Check the spelling.
Action: Check that any custom tasks/types have been declared.
Action: Check that any <presetdef>/<macrodef> declarations have taken place.

任何人都可以看到我的构建文件有什么问题吗？

你有：

<classpath>
     <pathelement path="${classpath}"/>
      <fileset dir="lib">
           <include name="**/*.jar"/>
       </fileset>
       <pathelement location="classes"/>
       <dirset dir="${build.dir}">
           <include name="apps/**/classes"/>
           <exclude name="apps/**/*Test*"/>
       </dirset>
       <filelist refid="third-party_jars"/>
  </classpath>

但是，你不能简单地将<classpath>抛弃其寂寞的自我。

您正在做的是创建一个 PATH ，可以在其他地方用作 CLASSPATH 。你可能想要：

<path id="class.path">
     <pathelement path="${classpath}"/>
      <fileset dir="lib">
          <include name="**/*.jar"/>
      </fileset>
      <pathelement location="classes"/>
      <dirset dir="${build.dir}">
          <include name="apps/**/classes"/>
          <exclude name="apps/**/*Test*"/>
      </dirset>
      <filelist refid="third-party_jars"/>
</path>

现在，当您需要指定类路径时，可以使用 PATH ：

   <javac srcdir="${src}"
        destdir="${build}"
        classpathref="class.path"/>

或者...

   <javac srcdir="${src}
        destdir="${build}">
        <classpath>
            <path refid="class.path"/>
        </classpath>
   </javac>

最后一个允许你根据需要添加多个类路径，有些人更喜欢它，因为它可以在需要时更容易更改类路径。
