I am experiencing problems when updating my tycho built product on macOS.
So this is my scenario:
I have a product built with tycho 1.0.0 based on Eclipse Oxygen
(org.eclipse.rcp_4.7.2.v20171130-0510) and an update-site containing a
newer version of my custom features. When I update this product eclipse
with the features on my update-site, the executable looses its executable
bit, so I cannot open my product anymore.
I debugged it remotely and found out that there is an exception thrown in
ChmodAction when trying to execute Runtime.getRuntime().exec("chmod",
"755", "path/to/executable"): java.io.IOException: Cannot run program
âchmodâ: error=2, No such file or directory
How can it be that chmod is not found (other binaries like "echo" are not
This problem occurs on several macOS systems. That said, I should mention
that we also have an older version of our product (based on Neon) for which
the update mechanism works fine.
Is this something known, or does anyone have a clue what I can further test
to spot the bug?
