Hi Niels,
Or, if you for some obscure reason need jdk 1.3:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<fork>true</fork>
<executable><your-jdk1.3-javac.exe></executable>
<compilerVersion>1.3</compilerVersion>
</configuration>
</plugin>
Did you try this [1] ?
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.3</source>
<target>1.3</target>
<compilerArguments>
<bootclasspath>${settings.localRepository}/com/sun/rt/1.3.1_08/rt-1.3.1_08.jar</bootclasspath>
</compilerArguments>
</configuration>
<dependencies>
<dependency>
<groupId>com.sun</groupId>
<artifactId>rt</artifactId>
<version>1.3.1_08</version>
</dependency>
</dependencies>
</plugin>
