JarCastingsystem-maven-plugin
This Maven plugin provides UnixSystem values like "uid" or "gid" as project properties.
Getting started
Just add the plugin to your Maven POM:
<plugin>
<groupId>org.fuin.smp</groupId>
<artifactId>system-maven-plugin</artifactId>
<version>0.1.0</version>
<!-- You can optionally change the prefixes
<configuration>
<generic-prefix>org.fuin.smp.</generic-prefix>
<unix-prefix>org.fuin.smp.unix.</unix-prefix>
</configuration>
-->
<executions>
<execution>
<phase>initialize</phase>
<goals>
<goal>read-system-information</goal>
</goals>
</execution>
</executions>
</plugin>
This will make all properties from UnixSystem available as project properties.
Here is a Docker Maven Plugin example on how to use the properties:
<plugin>
<groupId>io.fabric8</groupId>
<artifactId>docker-maven-plugin</artifactId>
<version>0.22.1</version>
<configuration>
<images>
<image>
<name>your/cool-image</name>
<run>
<volumes>
<bind>
<volume>${project.build.directory}:/usr/src/result</volume>
</bind>
</volumes>
<user>${org.fuin.smp.uid}:${org.fuin.smp.gid}</user>
</run>
</image>
</images>
</configuration>
</plugin>
This starts the image with the local user's UID and GID and files written into '${project.build.directory}' will have exactly that owner and group.
Available Properties
Generic
| Property | Description |
|---|---|
| org.fuin.smp.uid | UID for the current user (String) |
| org.fuin.smp.gid | GID for the current user (String) |
| org.fuin.smp.username | Username for the current user (String) |
UnixSystem
| Property | Description |
|---|---|
| org.fuin.smp.unix.gid | GID for the current Unix user (long) |
| org.fuin.smp.unix.groups | Supplementary groups for the current Unix user (long[]) |
| org.fuin.smp.unix.uid | UID for the current Unix user (long) |
| org.fuin.smp.unix.username | Username for the current Unix user (String) |
Limitations
Currently only Unix like systems are supported. It should also be possible to include NTSystem but somehow the class was missing in my local Java 8 JRE and I hadn't enough time to investigate this. Any help welcome.
