使用ant和build.xml错误

Question

当我尝试在GL服务器上运行我的程序时，出现错误。另外，我们有两个软件包，一个是所有软件包，另一个是内含Driver.java的驱动程序包。它运行程序。

BUILD FAILED 目标“运行”在项目“自动填写”中不存在。

这是为什么？这里是我的build.xml

<?xml version="1.0" encoding="UTF-8" standalone="no"?>

我已经在这里重新格式化您的build.xml。有一些问题吧：

<?xml version="1.0" encoding="UTF-8" standalone="no"?> 
<project basedir="." default="build" name="AutoFill"> 
    <property environment="env"/> 
    <property name="debuglevel" value="source,lines,vars"/> 
    <property name="target" value="1.7"/> 
    <property name="source" value="1.7"/> 
    <path id="AutoFill.classpath"> 
     <pathelement location="bin"/> 
    </path> 

    <target name="init"> 
     <mkdir dir="bin"/> 
     <copy includeemptydirs="false" todir="bin"> 
      <fileset dir="src"> 
       <exclude name="**/*.launch"/> 
       <exclude name="**/*.java"/> 
      </fileset> 
     </copy> 
    </target> 

    <target name="clean"> 
     <delete dir="bin"/> 
    </target> 

    <target name="cleanall" depends="clean"/> 

    <target name="build" 
     depends="build-subprojects, build-project"/> 

    <target name="build-subprojects"/> 

    <target name="build-project" 
     depends="init"> 
     <echo message="${ant.project.name}: ${ant.file}"/> 
     <javac debug="true" 
      debuglevel="${debuglevel}" 
      destdir="bin" 
      includeantruntime="false" 
      source="${source}" 
      target="${target}"> 
      <src path="src"/> 
      <classpath refid="AutoFill.classpath"/> 
     </javac> 
    </target> 

    <!-- Something happened here... --> 
    <target 
     description="Build all projects which reference this project. Useful to "/> 
    <!-- includeantruntime="false" source="${source}" target="${target}"> --> 

    <!-- Something happened to the name of this target -->

我不知道你是否miscopied它，但它根本就不是一个有效的Ant构建文件，因为它现在站立。你可能想检查你的帖子，看看你是否错过了任何东西。

您的错误非常简单。您没有名为run的目标。我不知道你为什么要执行它。 （也许是在被搞砸你的build.xml的部分

有效的目标是：

• 初始化
• 干净
• cleanall
• 构建
• 建设项目
• build-subprojects
• init - ???（Target nam e不完整）
• build-eclipse编译器（无效的目标名称。不能包含空格）
• MaxHeap（Java可执行文件）
• 驱动程序（Java可执行文件）

如果你试图编译这个项目，你要运行的build-project或build目标，而不是run。 （build-project和build都做同样的事情）。

如果您尝试运行某个程序，MaxHeap和Driver是build.xml中唯一的两个Java可执行目标。

因此，您可能需要执行目标build，然后执行Driver或MaxHeap。
