I'm using m2 v2.0 and attempting to compile 1.3.1 source with a 1.4.x or

1.5.x JDK. Error msg: "javac: invalid flag: -source". I've found

several references to this on mailing list, but no definitive solution

yet.

My current compiler config:

<plugin>

<groupId>org.apache.maven.plugins</groupId>

<artifactId>maven-compiler-plugin</artifactId>

<configuration>

<executable>C:\Java\jdk1.3.1_15\bin\javac</executable>

<fork>true</fork>

<verbose>true</verbose>

<includes>

</includes>

</configuration>

</plugin>

Any insight is much appreciated.

    • Hi,

      you write that you want to compile with a JDK 1.4.x or 1.5.x but in the

      plugin configuration you give a path to a JDX 1.3.x.

      A quick look at

      does not

      mention a '-source' option of the javac of JDK 1.3, hence the error.

    • I am executing M2 using 1.5.x, but attempting to fork a 1.3.1 process to

      do the actual compile.
