dev mode: "option --source cannot be used together with --release" - dev mode compile doesn't collapse source/target/release options like compiler plugin does

[scottkurz]

If I add the POM properties

        <maven.compiler.source>11</maven.compiler.source>
        <maven.compiler.release>17</maven.compiler.release>
        <maven.compiler.target>14</maven.compiler.target>

(ignoring whether these values really make sense or not)

and do mvn -X compile I'll get:

[DEBUG] Command line options:
[DEBUG] -d ..... -g -nowarn --release 17 -encoding UTF-8

I.e. the source + target options will be dropped and ignored and the release option will be passed to javac.

In dev mode, though, we get:

[ERROR] Error compiling Java files: error: option --source cannot be used together with --release

I'm thinking dev mode should behave more like the compiler plugin here (though I don't see this documented specifically at: https://maven.apache.org/plugins/maven-compiler-plugin/compile-mojo.html)
