Php Phing只执行默认目标

我对Phing有意见。他只做默认的工作。有没有人遇到过这样的行为？该环境在Windows 10上工作。 谢谢你的帮助

<?xml version="1.0" encoding="UTF-8"?>
<project name="Test" default="start">
    <!-- ============================================  -->
    <!-- Target: start                                 -->
    <!-- ============================================  -->
    <target name="start">
        <echo msg="Start build" />
    </target>
    <!-- ============================================  -->
    <!-- Target: prepareDirectory                      -->
    <!-- ============================================  -->
    <target name="prepareDirectory" depends="start">
        <echo msg="Making directory build ./build" />
        <mkdir dir="./build" />
        <echo msg="Making directory install ./install" />
        <mkdir dir="./install" />       
    </target>       
    <!-- ============================================  -->
    <!-- Target: build                                 -->
    <!-- ============================================  -->
    <target name="build" depends="prepareDirectory">
        <echo msg="Copying files to build directory..." />

        <echo msg="Copying ./about.php to ./build directory..." />
        <copy file="./about.php" tofile="./build/about.php" />

        <echo msg="Copying ./browsers.php to ./build directory..." />
        <copy file="./browsers.php" tofile="./build/browsers.php" />

        <echo msg="Copying ./contact.php to ./build directory..." />
        <copy file="./contact.php" tofile="./build/contact.php" />
    </target>
</project>

您需要以另一种方式设置依赖项。目标“开始”不会用当前代码触发任何其他目标

试试这个：

<?xml version="1.0" encoding="UTF-8"?>
<project name="Test" default="build">
    <!-- ============================================  -->
    <!-- Target: start                                 -->
    <!-- ============================================  -->
    <target name="start">
        <echo msg="Start build" />
    </target>
    <!-- ============================================  -->
    <!-- Target: prepareDirectory                      -->
    <!-- ============================================  -->
    <target name="prepareDirectory" depends="start">
        <echo msg="Making directory build ./build" />
        <mkdir dir="./build" />
        <echo msg="Making directory install ./install" />
        <mkdir dir="./install" />       
    </target>       
    <!-- ============================================  -->
    <!-- Target: build                                 -->
    <!-- ============================================  -->
    <target name="build" depends="prepareDirectory">
        <echo msg="Copying files to build directory..." />

        <echo msg="Copying ./about.php to ./build directory..." />
        <copy file="./about.php" tofile="./build/about.php" />

        <echo msg="Copying ./browsers.php to ./build directory..." />
        <copy file="./browsers.php" tofile="./build/browsers.php" />

        <echo msg="Copying ./contact.php to ./build directory..." />
        <copy file="./contact.php" tofile="./build/contact.php" />
    </target>
</project>

执行顺序为：start->prepareDirectory->build

希望能成功

它起作用了。谢谢你的帮助。我已经理解了默认目标的工作原理。对此我很抱歉。我是“StackOverflow”的新手。我还不知道所有的机制。
