使用ant和build.xml误差

Question

当我试图在GL服务器上运行我的程序时，我会得到一个错误。另外，我们有两个包，一个是所有的东西，另一个是包含Driver.java的驱动程序包。它运行程序。

项目"AutoFill“中不存在生成失败目标"run”。

为什么会这样呢？这是我的build.xml

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

          To include a user specific buildfile here, simply create one in the same

我在这里重新格式化了你的build.xml。它存在一些问题：

<?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... -->

我不知道您是否错误地复制了它，但是现在它根本不是一个有效的Ant构建文件。你可能想检查一下你的帖子，看看你有没有遗漏任何东西。

你的错误是很直接的。您没有一个名为run的目标。我不知道你为什么要执行它。(也许是在你的build.xml的那部分被搞砸了。

有效的目标是：

• 初始化
• 打扫
• 清洗剂
• 构建
• 建设项目
• 建设-次级项目
• 在-？(目标名称不完整)
• 构建eclipse编译器(无效的目标名称)。不能包含空格)
• MaxHeap (Java可执行)
• 驱动程序(Java可执行)

如果试图编译此项目，则希望运行build-project或build目标，而不是run。( build-project和build都做同样的事情)。

如果您试图运行某个程序，MaxHeap和Driver是build.xml中仅有的两个可执行目标。

因此，您可能希望执行目标build，然后执行Driver或MaxHeap。
