无法识别Ant4Eclipse中的工作区in

Question

这是我的构建文件：

<project name="ant-in-eclipse" basedir="."
         xmlns:ant4eclipse="antlib:org.ant4eclipse"
         xmlns:antcontrib="antlib:net.sf.antcontrib" default="compileAndJar" >

  <taskdef uri="antlib:net.sf.antcontrib"
           resource="net/sf/antcontrib/antlib.xml" />

  <!-- define ant4eclipse tasks -->
  <taskdef uri="antlib:org.ant4eclipse"
           resource="org/ant4eclipse/ant/antlib.xml" />

  <import file="/data/temp/ANT/ANT4/macros/a4e-jdt-macros.xml"/>
  <target name="compileAndJar">
      <macrodef name="build">
          <attribute name="workspaceDirectory" default="deploy" />
          <sequential>
              <echo>Hi</echo>
          </sequential>
      </macrodef>

      <buildJdtProject workspaceDirectory="${workspaceDirectory}"
                       projectname="wfn-common.jar">
      <finish>
          <jar destfile="deploy/wfn-common.jar">
              <ant4eclipse:jdtProjectFileSet destination="."
               projectname="${buildJdtProject.project.name}" />
          </jar>
      </finish>
      </buildJdtProject>
   </target>
</project>

我得到了这个错误

有谁能帮帮我吗？

错误在您导入的文件中：

<导入file="/data/temp/ANT/ANT4/macros/a4e-jdt-macros.xml"/>

我猜您的buildJDTProject目标是在那里定义的，并且它的定义方式有一个错误。

• 查看第105行文件/data/temp/ANT/ANT4/macros/a4e-jdt-macros.xml
• Look，这就是您的构建

失败的地方

我猜它会是buildJDTProject的目标。我猜目标包含workspaceid属性，这似乎是非法的。

您可以删除该属性，或者弄清楚为什么要将其放在第一位。也许它适用于不同版本的ant jdt库？

还有两个猜测(我对ant4eclipse BTW不熟悉)。关于ant4eclipse的buildJdtProject任务...

这份文件说

必须指定'workspaceDirectory‘或'workspaceId’

您将在构建脚本的目标中传递workspaceDirectory。可能默认情况下在该导入文件的宏中指定了workspaceId。如果是这样的话，也许你最终同时定义了workspaceDirectory和workspaceId，这是非法的。然而，这个想法与您得到的错误消息不匹配。

或者，也许ant4eclipse对属性名称区分大小写。这对于Ant来说并不常见，它通常是不区分大小写的。但是ant4eclipse文档给出的属性名为workspaceId，您的错误消息显示workspaceid不受支持。因此，可以尝试更改导入文件中的大小写。
