I just tried using this method except with
<compilerVersion>1.4</compilerVersion> and without <fork>true</fork> since
javac fails if I use fork (probably due to
http://jira.codehaus.org/browse/MCOMPILER-22).
It doesn't work. I'm still getting the "java.lang.NoSuchMethodError:
java.math.BigDecimal: method <init>(I)V not found" exception, meaning
maven is still using the 1.5 JDK to compile despite those settings. Is
forking absolutely necessary to use an older JDK?
Using:
<configuration>
<source>1.4</source>
<target>1.4</target>
<compilerArguments>
<bootclasspath>C:/j2sdk1.4.1/jre/lib/rt.jar;C:/j2sdk1.4.1/jre/lib/jce.jar</bootclasspath>
</compilerArguments>
</configuration>
works well but seems like a hack. Is this the proper way of using another
JDK for compilation?

Re: [M2] Compiling with JDK 1.4
Check this out to actually use another JDK
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<fork>true</fork>
<compilerVersion>1.3</compilerVersion>
<executable>C:/Program
Files/Java/jdk1.3.1_18/bin/javac</executable>
<!--
A portable way using environment variables
<executable>${JAVA_1_3_HOME}/bin/javac</executable>
-->
</configuration>
</plugin>

No good. I've known too many Spaniards.
