<fileSet>
    <directory>${project.build.directory}/tar_content/stackcontents/</directory>
    <outputDirectory>scripts/data/rpms/</outputDirectory>
    <includes>
        <include>%regex[ABC502(3|4)]-*.rpm</include>
    </includes>
    <fileMode>0755</fileMode>
    <directoryMode>0755</directoryMode>
</fileSet>

推荐答案

使用

When you use a regular expression to include or exclude files with the %regex[...] syntax, all of the expression should be composed of the regular expression. You cannot mix a regular expression part with a normal part when it is used to match files.

因此，您需要使用

<fileSet>
    <directory>${project.build.directory}/tar_content/stackcontents/</directory>
    <outputDirectory>scripts/data/rpms/</outputDirectory>
    <includes>
        <include>%regex[ABC502(3|4)-.*?\.rpm]</include>
    </includes>
    <fileMode>0755</fileMode>
    <directoryMode>0755</directoryMode>
</fileSet>

这将包括从ABC5023或ABC5024开始的所有RPM文件.

This will include all RPM files starting by ABC5023 or ABC5024.
