Need to link a plugin against Java 1.4 [message #641916]

Hello,

sadly, I have the need to link one of our plugins against the rt.jar of
Java 1.4. Is there a way with Tycho to do this?

I tried to configure the maven-osgi-compiler-plugin like in the snippet
below... without success. I tried it via the plugin and via the parent pom.

<pluginManagement>
<plugins>
<plugin>
<groupId>org.codehaus.tycho</groupId>
<artifactId>maven-osgi-compiler-plugin</artifactId>
<version>0.10.0</version>
<configuration>
<source>1.4</source>
<target>1.4</target>
<fork>true</fork>

<executable>D:\bin\java\x86\j2sdk1.4.2_12\bin\javac.exe</executable >
</configuration>
</plugin>
</plugins>
</pluginManagement>

Kind regards,
Bernd Vogt

you picked the wrong groupId.

It should be org.sonatype.tycho (since tycho 0.6.0)

Apart from that your configuration should be OK.

> It should be org.sonatype.tycho (since tycho 0.6.0)

Thanks for the hint! Unfortunately, this leads to the next problem:

[ERROR] Failed to execute goal
org.sonatype.tycho:maven-osgi-compiler-plugin:0.10.0:compile
(default-compile) on project de.visualrules.runtime: Fatal error
compiling: compileoutOfProcess not supported -> [Help 1]

A short code review has confirmed that Tycho 0.10.0 (JDT compiler mojo)
doesn't support forking.

As a workaround I have tried to configure the maven-osgi-compiler-plugin
in a way that it uses the javac compiler from the maven-compiler-plugin.
With the result that javac couldn't resolve any class from my dependencies.

Is there any way to tell the maven-osgi-compiler-plugin against which
rt.jar he has to compile?

In PDE build I have to map specific jars to an execution environment:

J2SE-1.4=/home/var/j2sdk1.4.2_19/jre/lib/rt.jar
J2SE-1.5=/home/var/jdk1.5.0_22/jre/lib/rt.jar
JavaSE-1.6=/home/var/jdk1.6.0_18/jre/lib/rt.jar

Kind regards,
Bernd

I got it! Configuring the bootclasspath argument of the JDT compiler
does the trick:

<pluginManagement>
<plugins>
<plugin>
<groupId>org.sonatype.tycho</groupId>
<artifactId>maven-osgi-compiler-plugin</artifactId>
<version>${tychoVersion}</version>
<configuration>
<compilerId>jdt</compilerId>
<compilerArguments>

<bootclasspath>D:\bin\java\x86\j2sdk1.4.2_12\jre\lib\rt.jar </bootclasspath>
</compilerArguments>
</configuration>
</plugin>
</plugins>
</pluginManagement>
