We handled this problem by creating a parent POM that all of our
projects inherit from with the following:
<plugin>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.5</source>
<target>1.5</target>
</configuration>
</plugin>
Then in the individual project you add:
<parent>
<artifactId>parent-artifact-name</artifactId>
<groupId>com.my.group</groupId>
<version>1.0</version>
</parent>
In a couple of projects, we needed to use 1.6 instead of 1.5, so then
you have to override the settings in a given child pom:
<build>
<plugins>
<plugin>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.6</source>
<target>1.6</target>
<fork>true</fork>
<executable>${JAVA_1_6_HOME}/bin/javac</executable>
<compilerVersion>1.6</compilerVersion>
</configuration>
</plugin>
</plugins>
</build>
Where JAVA_1_6_HOME is an environment variable that provides the home
of
a different java version.

Subject: Re: Default java source version
hi jason,
yes i know that and i have that section in my POM. what i want is to
override the default of java 1.3 so i don't have to do that in all my
project POM files which is tedious. that's why i was asking for a way to
configure it in the settings.xml.
i suppose 1.3 is not hardcoded and can be changed via some property or
some other configuration... no?
cheers,
severin
