I'm seeing an error with the packaging plugin when building inside a Git worktree  (other than the default worktree created by the initial clone).
[ERROR] Failed to execute goal org.eclipse.tycho:tycho-packaging-plugin:0.22.0:package-plugin (default-package-plugin) on project com.example.myproj: IO exception trying to create git repo : repository not found: /d01/sandboxes/myproj/.git/worktrees/myproject.mybranch
In a worktree, the .git is not a folder, but instead a text file containing the path that is in the error. The stacktrace shows the error is coming from JGit
Caused by: org.apache.maven.plugin.MojoExecutionException: IO exception trying to create git repo

Bugzilla has nothing for Tycho product with search for "worktree" other than
https://bugs.eclipse.org/bugs/show_bug.cgi?id=419520, which was resolved in 0.19 and doesn't relate to tycho-packaging-plugin or building in a worktree.
JGit support for multiple worktrees is not yet available, there is a draft which is still unfinished
