Re: [tycho-user] Forking in combination with BREE (Re: should <showWarni

[Johan Compagner <jcompagner@xxxxxxxxxx>]

i finally figured it out why i had so many problems with BREE

so for anybody that has the same thing i hope google will pick this up

i had 2 quite simple plugin kind of projects, they are more plugins because they are used by "real" eclipse plugins

but 1 of them is a bit bigger uses one or 2 other plugins. So that one has in its pom file a p2 repository so using this:

<eclipse.url>http://download.eclipse.org/eclipse/updates/4.13/</eclipse.url>

when i did add <useJDK>BREE</useJDK>

it worked for that one 

but the other project is much simpler that doesn't have any repo to build, it doesn't have any plugin dependencies

This works fine for building with tycho

But at the moment you add  <useJDK>BREE</useJDK> and JAVA_HOME (that maven uses to run) is not java8 but already java12 or something like that.

then i still get that error that JavaSE-12 execution environment is not found, even if everything is correctly configured to use JavaSE-1.8

but with -X i looked carefully what now the difference is.. this happens with the one that goes wrong:

and then it starts to compile fine.

So it seems that it needs to have a eclipse update site to get to some Execution environment

But both are saying 

  [DEBUG] Using execution environment 'JavaSE-12' configured in current execution environment 

but i wonder what that is really about.. that seems to be something for that target platform.

It seems the compiler really uses something else. because if i make a type on the toolchain.xml and let it run again

Then the output above is the same..

But the compiler bombs out: (it seems to be nicely configured)

See http://maven.apache.org/guides/mini/guide-using-toolchains.html

and when that is correct and i see this:

INFO] Compiling 327 source files to C:\Users\jcomp\git\servoy_master\servoy-js-engine\org.eclipse.dltk._javascript_.rhino\target\classes
[DEBUG] JDT compiler args: 

and I analyse the args then that is correct it compiles against the jdk1.8 classpath

also I see that -warn:none is added to the compiler args but still it gives me loads of warnings

so it seems that is not a tycho problem but somewhere a configuration or jdk compiler problem?

phhh, thx..

that did fix the problem of not finding the toolchain, i don't get it i thought i copied it straight from the manifest.mf

but now i am back that it fails with "compileoutOfProcess not supported"

and without the fork param but with:

 <showWarnings>false</showWarnings>
<compilerArgument>-warn:none</compilerArgument>

it still gives all the warnings..

but at least now it doesn't matter what JAVA_HOME is and where you run Maven with.

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?
