Re: [tycho-user] Forking in combination with BREE (Re: should <showWarnings>false</showWarnings> work?)
|
I don't know much about the compiler stuff, just noticed that the error
complains about:
JavaSE-1.8 not found
and in the xml the id is 'JavaSE-8' may thats a problem?

Hi,
i tried a few things more to get my warnings out and playing with useJDK
I have to seem to be missing some docs.. or the docs really needs to be
updated of the compiler plugin, for example fork:
https://www.eclipse.org/tycho/sitedocs/tycho-compiler-plugin/compile-mojo.html#fork
there is nothing that says there in the docs that that needs some more
stuff
Because if you just enabled that you will get:
Failed to execute goal
org.eclipse.tycho:tycho-compiler-plugin:1.4.0:compile (default-compile)
on project servoy_base: Fatal error compiling: compileoutOfProcess not
supported -> [Help 1]
Then i though hmm maybe this will work with <useJDK>BREE</useJDK> that
we then will fork out, if i also add that:
[ERROR] Failed to execute goal
org.eclipse.tycho:tycho-compiler-plugin:1.4.0:compile (default-compile)
on project servoy_base: useJDK = BREE configured, but no toolchain of
type 'jdk' with id 'JavaSE-1.8' found. See
http://maven.apache.org/guides/mini/guide-using-toolchains.html -> [Help 1]
But as far as i know i have it all configured, i have a toolchains.xml
file in my .m2 dir:
<toolchains>
<!-- JDK toolchains -->
<toolchain>
<type>jdk</type>
<provides>
<id>JavaSE-8</id>
</provides>
<configuration>
<jdkHome>c:/javatools/jdk18/</jdkHome>
</configuration>
</toolchain>
</toolchains>
i have then also enabled the toolchain plugin:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-toolchains-plugin</artifactId>
<version>3.0.0</version>
<executions>
<execution>
<goals>
<goal>toolchain</goal>
</goals>
</execution>
</executions>
<configuration>
<toolchains>
<jdk>
<id>JavaSE-8</id>
</jdk>
</toolchains>
</configuration>
</plugin>
the output of that plugin says that it did find it:
[INFO] --- maven-toolchains-plugin:3.0.0:toolchain (default) @
servoy_base ---
[INFO] Required toolchain: jdk [ id='JavaSE-8' ]
[INFO] Found matching toolchain for type jdk: JDK[c:/javatools/jdk18/]
But still i get the error above...
So how is this supposed to work?
What steps am i missing here?

Hi,
i have this:
<groupId>org.eclipse.tycho</groupId>
<artifactId>tycho-compiler-plugin</artifactId>
<version>${tycho.version}</version>
<configuration>
<showWarnings>false</showWarnings>
xxxx
but it will show warnings no matter what
i also tried to run with:
mvn clean install -Dmaven.compiler.showWarnings=false
but still a lot of warnings..
The same thing is that i can't get that <useJDK> to work
i have added this in my toolchains.xml file:
<toolchain>
<type>jdk</type>
<provides>
<id>JavaSE-8</id>
</provides>
<configuration>
<jdkHome>c:/javatools/jdk18/</jdkHome>
</configuration>
</toolchain>
and then use
<useJDK>BREE</useJDK>
in the configuration of the tycho compiler plugin
and in the manifest i do have:
Bundle-RequiredExecutionEnvironment: JavaSE-1.8
But no matter what if i then run maven (java.home property) with java12
it will start to complain it can't find or use it:
Could not find specification for custom execution environment
profile 'JavaSE-12'
also the -X of maven doesn't really tell that much, i had hopped for
a bit more output of the compiler plugin..
