Re: [tycho-dev] migrating from Tycho 1.7 to 2.3

[Guillaume Dufour <guillaume.duff@xxxxxxxxx>]

Hello,

here is my example

tycho-demo/itp04-rcp at toolchain · Dufgui/tycho-demo (github.com)

I launch the build with the following command:

 mvn clean install -X --global-toolchains toolchains.xml

My JAVA_HOME point to a jdk 11. And my toolchain to java 8.

And I see he fail to compile due to some classe remove from jdk in 11 but present in jdk 8.

So I think he compile with the wrong javac. no ?

You should at least share a more complete error message, and as best a
minimal example that reproduces the problem (no need to share the actual
code).
