Ant 当文件集包含与globmapper模式不匹配的文件时，如何强制执行错误

下面的代码演示了使用

ant

文件

copy

任务和

globmapper

的行为。我想复制一组文件。复制重命名所需的某些文件时，请选择与模式匹配的文件。我认为匹配模式的文件将以新名称复制，而其他文件将以原始名称复制

这是错误的：如果源集包含与模式不匹配的文件，它们将被忽略

<project name="trial" default="test" basedir=".">
    <target name="test">
        <property name="mydir" value="${java.io.tmpdir}/demo/src"/>
        <mkdir dir="${mydir}" />
        <touch file="${mydir}/abc0.txt"/>
        <touch file="${mydir}/abc1.java"/>
        <touch file="${mydir}/abc2.java"/>

        <property name="dest" value="${java.io.tmpdir}/demo/dest"/>
        <copy todir="${dest}" >
            <fileset dir="${mydir}">
                <include name="**/*.java"/>
                <include name="**/*.txt"/>
            </fileset>
            <globmapper from="*.txt" to="*.bak"/>
        </copy>
    </target>

    <target name="clean" >
        <delete dir="${java.io.tmpdir}/demo"/>
    </target>
</project>

调试的输出

ant-v

我现在理解了行为（以及可能的修复），但我能强迫ant在这种情况下出错吗

A包含应用于文件的嵌套映射器，直到其中一个嵌套映射器匹配为止

输出

[copy]将3个文件复制到C:\cygwin\tmp\demo\dest
[复制]将C:\cygwin\tmp\demo\src\abc0.txt复制到C:\cygwin\tmp\demo\dest\abc0.bak
[复制]将C:\cygwin\tmp\demo\src\abc1.java复制到C:\cygwin\tmp\demo\dest\abc1.java
[复制]将C:\cygwin\tmp\demo\src\abc2.java复制到C:\cygwin\tmp\demo\dest\abc2.java

请注意，

abc0.txt

的扩展名更改为

.bak

，但其他文件的

.java

扩展名保持不变

解释 在上面的示例中，

包含两个映射器：

对于

abc0.txt

：

abc0.txt

匹配

，因此应用

来获取

abc0.bak

由于已经存在匹配项，

被跳过

对于

abc1.java

：

abc1.java

与

不匹配，因此跳过此映射程序

因为还没有匹配，所以应用了
