Ant 未创建目录

Question

我是 Ant 构建脚本的新手。我正在尝试做以下事情

1. 删除构建目录
2. 创建构建目录
3. 编译代码
4. 为项目中的每个包创建 jar 文件

为此，我编写了以下代码

<?xml version="1.0"?>
<project name="test" basedir=".">
    <property name="build.lib" value="dist"/>
    <property name="prefix" value="XXX"/>
    <property name="src.dir" value="src"/>
    <property name="build.dir" value="build"/>
    <property name="build.classes" value="${build.dir}/classes"/>
    <property name="jar.dir" value="${build.dir}/jar"/>
    <path id="compile.classpath">
        <fileset dir="OpenJPA_lib_jar">
            <include name="*.jar"/>
        </fileset>
    </path>
<macrodef name="build_jar">
    <attribute name="name"/>
    <sequential>
        <jar destfile="${build.lib}/${prefix}-@{name}.jar">
            <fileset dir="${build.classes}">
                <include name="zumigo/geofence/@{name}/**"/>
            </fileset>
        </jar>
    </sequential>
</macrodef>
    <target name="clean">
        <delete dir="${build.dir}"/>
    </target>
<echo message="Build dir = ${build.dir}"/>
    <target name="prepare">
        <mkdir dir="${build.dir}"/>
    </target>
    <target name="compile" depends="prepare">
        <javac destdir="${build.classes}" debug="true" srcdir="${src.dir}">
            <classpath refid="compile.classpath"/>
        </javac>
    </target>
<target name="run" depends="compile">
        <build_jar name="common"/>
    <build_jar name="dal"/>
    <build_jar name="databeans"/>
    <build_jar name="dataobject"/>
    <build_jar name="dto"/>
    <build_jar name="exception"/>
    </target>
</project>

当我使用详细选项在命令行上执行 ant 脚本时，它给了我以下输出

Apache Ant(TM) version 1.8.3 compiled on February 26 2012

我什至尝试在 eclipse 中调试脚本。调试点设置在"准备"目标处，当我们按 F5 时，它会退出调试。它不显示任何错误消息。

谁能让我知道剧本有什么问题？

你没有告诉蚂蚁要运行哪个目标。指定-p（或选择要在 Eclipse Ant 运行器中运行的目标）或定义要在 <project> 标记中运行的缺省目标。
