Re: [tycho-user] [tycho-dev] migrating from Tycho 1.7 to 2.3
Thanks mickael,

I add useJDK=BREE without better result (i already test it but not push the commit) but without more success.

Here is the list of my warnings:
[WARNING] Bundle-ClassPath entry runtime_registry_compatibility.jar does not exist in C:\Users\gdufour\.m2\repository\p2\osgi\bundle\org.eclipse.equinox.registry\3.6.0.v20150318-1503\org.eclipse.equinox.registry-3.6.0.v20150318-1503.jar

But I think we need a javax.xml.bind, and not only the javax.xml. But javax.xml.bind is inside my target, the package is imported but it's seems not enough.

Have you tried enabling the log output? Do you see some warnings?
In youf case, Tycho is using the JavaSE-1.8 to resolve dependencies (using the JavaSE-1.8.profile built-in) so it doesn't add the javax.xml* bundles to build path, but then use a newer Java version to compile, that doesn't have this packages. Basically, it's not using your toolchain.
See http://www.eclipse.org/tycho/sitedocs/tycho-compiler-plugin/compile-mojo.html#useJDK , building against another JDK requires to set `useJDK=BREE` and to define the associated JDK in toolchains.xml.

I read this many times but sorry don't fully understand what is expected.
So I try a new commit but it's still fail with it.


With exactly the same error:
[ERROR] The import javax.xml.bind cannot be resolved

even if I:
- import the package in the manifest,
- declare the executionEnvironment in the target (repository)
- set requireJREPackageImports to true

really sorry to don't understand

Hi,

Basically, the BREE is only used to set the source/compile level in the compiler and isn't used to set the target-platform/library level. For such package that have been removed from a java version to the other, you should make sure those packages are imported in MANIFEST.MF. Against Java 8, they'll resolve to the package in the execution environment; against Java 11, they'll resolve to the javax.xml bundles.
