MCA not working on mac
Describe the bug MCA version 1.17.3 is not opening on mac
To Reproduce Steps to reproduce the behavior:
- download the jar file
- open it
- gives the message: "Java application launch failed. Check Console for possible error messages related to "/Users/name/Downloads/mcaselector-1.17.3"."
Expected behavior the program would run
Environment (please complete the following information):
- OS: MacOS
- Java version: 17
- Version of MCA Selector 1.17.3
When run from a command line using java -jar the message is: Error: LinkageError occurred while loading main class net.querz.mcaselector.Main java.lang.UnsupportedClassVersionError: net/querz/mcaselector/Main has been compiled by a more recent version of the Java Runtime (class file version 61.0), this version of the Java Runtime only recognizes class file versions up to 57.0
I am running Java Version 8 Update 333 (build 1.8.0_333-b02)
That error indicates the class files have been compiled with a newer version of Java than the version you are running it with. You probably need to upgrade your java runtime.
I got it to work by using the version of Java listed on the install page (zulu17.30.51-ca-fx-jre17.0.1-macosx_x64.zip). That appears to report:
openjdk version "17.0.1" 2021-10-19 LTS OpenJDK Runtime Environment Zulu17.30+51-CA (build 17.0.1+12-LTS) OpenJDK 64-Bit Server VM Zulu17.30+51-CA (build 17.0.1+12-LTS, mixed mode, sharing)
When I download the latest version of Java from java.com (today), it reports:
java version "1.8.0_333" Java(TM) SE Runtime Environment (build 1.8.0_333-b02) Java HotSpot(TM) 64-Bit Server VM (build 25.333-b02, mixed mode)
The versioning of Java is very confusing.
Same problem, I'm using the latest Java runtime (same as above). I redownloaded and reopened MCA Selector after hitting this bug and then having to upgrade my Java runtime. Same error.
I too am having the same issue. Running macOS Monterey Version 12.4 with Java Version 8 Update 333 and get the error: 'Java application launch failed. Check Console for possible error messages related to "/Users/name/Downloads/mcaselector-1.17.3' when trying to open mcaselector-1.17.3.jar file.

Go to the command line, use cd Users/name/Downloads/ and then use java -jar mcaselector-1.17.3.jar and tell me what the console prints

I see also that mcaselector-2.0.jar is now available. I've downloaded and tried the same command for that too.

Update Java. mcaselector was compiled with a newer version of java.
ie Exception in thread "main" java.lang.UnsupportedClassVersionError: net/querz/mcaselector/Main has been compiled by a more recent version of the Java Runtime (class file version 61.0), this version of the Java Runtime only recognizes class file versions up to 52.0
is saying Uh Oh, This program was made with a newer version of Java, With class version 61. I only support class versions up to Class Version 52
Here is a link from Oracle you may find helpful https://docs.oracle.com/javase/10/install/installation-jdk-and-jre-macos.htm#JSJIG-GUID-0071963E-D247-4D15-BF49-AD19C7260740
Okay, so I think what your saying is that it won't work because you don't support it? If this is the case, will you support it in the future or will I not be able to use mcaselector again?
Java has different versions, similarly to how minecraft updates. To get the new blocks (or in this case, the program access), you need to update java. Mac is supported, you just need to update java. Look up a youtube video on how to do so
It is not about updating Java. It is about using the right/supported version. Use the "zulu" version from the install page.

I've tried looking for the 'Zulu' version but can't find it. Are you able to send me the link?

I have already done this.
