How to see the full dependencies used during compile for a specific project

[peterkir]

Hi all,
I'm building a huge project and get a compilation error during tycho build on missing import package due to accessibility issues.
In Eclipse everything is compiling fine. Project is using Java17.

[ERROR]         import javax.xml.namespace.QName;
[ERROR]                ^^^^^^^^^^^^^^^^^^^
[ERROR] The package javax.xml.namespace is accessible from more than one module: <unnamed>, java.xml

The target platfrom state view does not contain a bundle containing this package.
How can I show the concrete dependencies used inside the tycho build compile stage?

Or is there an alternative solution to find the "" module exporting this package?

Yes this is very annoying and the only real solution I found is to migrate to jakarta namespace :-\

But there is a little "hack" (or feature?) to set the following JDT options so the compiler just ignores the problem, by open the file .settings/org.eclipse.jdt.core.prefs and add

org.eclipse.jdt.core.compiler.ignoreUnnamedModuleForSplitPackage=enabled

See https://stackoverflow.com/a/75548788

Beside that Tycho has a p2 variant of the maven dependency:tree mojo with tycho-p2-plugin:dependency-tree

It's part of the JDK
