java - 使用 Maven 将文件转换为 UNIX 格式

Question

我有一个在 Windows 环境中开发的应用程序。应用程序本身被部署到 Linux 环境中。每次部署此应用程序时，我都必须使用 dos2unix 将可执行文件转换为 UNIX 格式。我最初认为这是由 Windows CP1252 编码引起的，所以我更新了 Maven 以将文件编码为 UTF-8。这并没有解决我的问题，我通过搜索这个站点很快发现这与回车和换行有关。有没有办法让 Maven 在构建过程中将所有文件转换为 UNIX 格式？我正在使用 Maven 2.2.1 和 Java 5。

Answer 1

The assembly plugin has a lineEnding option which can be used to control the line-ending of the files for a given fileSet. This parameter is precisely there to do what you want. Ultimately, you could build zip archives with with CRLF lines and tar.gz archives with LF lines.

E.g.

...
<fileSet>
    <directory>${basedir}/src/main/build/QA</directory>
    <outputDirectory>/bin</outputDirectory>
    <includes>
        <include>start.sh</include>
    </includes>
    <lineEnding>unix</lineEnding>
</fileSet>
...

Possible values at this time include:

• "keep" - Preserve all line endings
• "unix" - Use Unix-style line endings (i.e. "\n")
• "lf" - Use a single line-feed line endings (i.e. "\n")
• "dos" - Use DOS-/Windows-style line endings (i.e. "\r\n")
• "windows" - Use DOS-/Windows-style line endings (i.e. "\r\n")
• "crlf" - Use carriage-return, line-feed line endings (i.e. "\r\n")

可以使用 Maven antrun插件调用fixcrlf ant 任务：
