Error: Unable to load or parse gradle file: Error (on Windows, but on Mac is okay) about trapeze

You just set it to wherever you have java installed, using the proper directory for JAVA_HOME https://confluence.atlassian.com/doc/setting-the-java_home-variable-in-windows-8895.html

[mlynch]

Can you try setting JAVA_HOME to C:\Program Files\Git\Library\Java\JavaVirtualMachines\jdk-15.0.2.jdk\Contents\Home and see if that works?

@mlynch
Ahhh that's my problem, I don't have that path on my Windows machine (I don't have the Library folder onwards).

I believe the default location for Java on Windows gets installed to a different path (I'm pretty sure I just did the default installation without changing paths) and so JAVA_HOME is:

C:\Users\hknaus>echo %JAVA_HOME%
C:\Program Files\Java\jdk-15.0.2\bin

If Trapeze is expecting the other path that you provided it would never work on Windows or I'm going to need to check the operation system that I'm building on and switch paths accordingly... or am I missing something else?

In our CI/CD scripts (which run on a Mac) we do set JAVA_HOME to /Library/Java/JavaVirtualMachines/jdk-15.0.2.jdk/Contents/Home (in case there are multiple instances installed and the machine's default is the latest version).

User error. Different environment, different JAVA_HOME paths.

Glad it's working, cheers

@mlynch I had two version of the JDK on my Windows machine (15.0.2, i.e. the one I need to use for this app, and 19).

javac -version kept returning 19, regardless of me setting JAVA_HOME to 15 or not.

So I figured I would uninstall 19 altogether and that would solve the issue, but it didn't. I still have the same issue so I closed this prematurely.

This is what I'm showing:

C:\Users\hknaus>java -version
java version "15.0.2" 2021-01-19
Java(TM) SE Runtime Environment (build 15.0.2+7-27)
Java HotSpot(TM) 64-Bit Server VM (build 15.0.2+7-27, mixed mode, sharing)

C:\Users\hknaus>javac -version
javac 15.0.2

C:\Users\hknaus>echo %JAVA_HOME%
C:\Program Files\Java\jdk-15.0.2\bin

C:\Users\hknaus>

The error is slightly different, looks like an additional \bin\java is being appended to the JAVA_HOME path somewhere:

@mlynch It looks like \bin\Java is being added to JAVA_HOME on line 399 of gradle-file.js which is line 510 in gradle-file.ts https://github.com/ionic-team/trapeze/blob/main/packages/project/src/android/gradle-file.ts

[mlynch]

Don't add bin to the end of JAVA_HOME

[hughknaus]

I swear there was something else that required the \bin on the path but I guess I'll find that one at a later time. ;)

@mlynch Thank you again, it's now running fine!
