|Re: [p2-dev] [tycho-user] Update on macOS fails to execute chmod|
cross-posting to p2-dev as this is happening in p2 code
chmod not being on the PATH seems strange to me.
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 found either)?
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?
