使用ant和build.xml錯誤

Question

當我嘗試在GL服務器上運行我的程序時，出現錯誤。另外，我們有兩個軟件包，一個是所有軟件包，另一個是內含Driver.java的驅動程序包。它運行程序。

BUILD FAILED 目標「運行」在項目「自動填寫」中不存在。

這是爲什麼？這裏是我的build.xml

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

      Any modifications will be overwritten. 
      To include a user specific buildfile here, simply create one in the same

我已經在這裏重新格式化您的build.xml。有一些問題吧：

<?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 --> 
    <target name="init-" 
     description="copy Eclipse compiler jars to ant lib directory"> 
     <copy todir="${ant.library.dir}"> 
      <fileset dir="${ECLIPSE_HOME}/plugins" 
       includes="org.eclipse.jdt.core_*.jar"/> 
     </copy> 
     <unzip dest="${ant.library.dir}"> 
      <patternset includes="jdtCompilerAdapter.jar"/> 
      <fileset dir="${ECLIPSE_HOME}/plugins" 
       includes="org.eclipse.jdt.core_*.jar"/> 
     </unzip> 
    </target> 

    <!-- Something happened to this target name --> 
    <target name="build-eclipse compiler" 
     description="compile project with Eclipse compiler"> 
     <property name="build.compiler" value="org.eclipse.jdt.core.JDTCompilerAdapter"/> 
     <antcall target="build"/> 
    </target> 

    <target name="MaxHeap"> 
     <java classname="proj3.MaxHeap" 
      failonerror="true" fork="yes"> 
      <classpath refid="AutoFill.classpath"/> 
     </java> 
    </target> 

    <target name="Driver"> 
     <java classname="driver.Driver"

我不知道你是否miscopied它，但它根本就不是一個有效的Ant構建文件，因爲它現在站立。你可能想檢查你的帖子，看看你是否錯過了任何東西。

您的錯誤非常簡單。您沒有名爲run的目標。我不知道你爲什麼要執行它。 （也許是在被搞砸你的build.xml的部分

有效的目標是：

• 初始化
• 乾淨
• cleanall
• 構建
• 建設項目
• build-subprojects
• init - ???（Target nam e不完整）
• build-eclipse編譯器（無效的目標名稱。不能包含空格）
• MaxHeap（Java可執行文件）
• 驅動程序（Java可執行文件）

如果你試圖編譯這個項目，你要運行的build-project或build目標，而不是run。 （build-project和build都做同樣的事情）。

如果您嘗試運行某個程序，MaxHeap和Driver是build.xml中唯一的兩個Java可執行目標。

因此，您可能需要執行目標build，然後執行Driver或MaxHeap。
