Convert files to UNIX format using Maven
I have an application that is developed in a Windows environment. The application itself gets deployed to a Linux environment. Each tim开发者_运维技巧e I deploy this application I have to convert executable files to UNIX format using dos2unix. I originally thought this was caused by the Windows CP1252 encoding, so I updated Maven to encode the files to UTF-8. This didn't solve my issue and I quickly found out that this has to do with carriage returns and line feeds by searching this site. Is there a way to have Maven convert all of the files to UNIX format during the build process? I am using Maven 2.2.1 and Java 5.
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")
You can use the Maven antrun plugin to call the fixcrlf ant task:
