[BUG] The inability to install Java automatically on Mac OS.

[TaigoStudio]

Describe the bug
The inability to install Java automatically on Mac OS.
During Java installation, the file installation path has jre.bundle/Contents/Home/ in it, which does not allow copying files to the runtimes folder

Environment (please complete the following information):

• OS: MacOS ARM
• CmlLib.Core Version: latest
• .NET version: net8

Additional context

Also, the manifest does not have Java 8 for Mac OS ARM, which does not allow you to run older versions. Is there anything we can do about it? Oracle has officially released a version for Mac OS ARM

I fixed this but not tested on mac yet. can you try the latest commit on dev branch?

you can specify JavaPath property of MLaunchOption when the library can't load a Java automatically.

[TaigoStudio]

It doesn’t work because this part has the installation path. If you remove it, everything will work

Here's the code that fixes it

Is it impossible to write a file into jre.bundle/Content/Home/? What error do you see? I don't understand what causes the error.

[AlphaBs]

It is normal behavior to install files into <game>/runtime/<mac>/<java>/jre.bundle/Contents/Home/bin/java.

The new IJavaPathResolver implementation can resolve the right java binary path.

[TaigoStudio]

I didn't look to see if changing this class helped. I thought that the installation path was fixed there, so I didn't run minecraft completely. Tomorrow I'll see if Java works with the modified path

[TaigoStudio]

yes, its fixed
