Seems like if I correctly set the JAVA_HOME to the java 17 home directory this error goes away, but I get

Edit: managed to fix it by running buildDependants first. However, now I can find no way to actually run it? From BUILD.md, I'm supposed to run gradle app:run, however that tries to download a full JDK for bundling. Is that really necessary for a debug build? Is there a way to build and run it quickly, with the existing JDK?

Also, BUILD.md contains no guide for command-line building.

Hi @babaissarkar, first of all, thank you for building Processing and giving detailled feedback!

What architecture are you running on, arm64 by chance? I've seen this issue of the preprocessor:ant-preproc appearing when I used any other JDK than 17 x64 edition. In any case this bug should be fixed by #957 which is almost ready to merge

To answer your other question, yes it would work with the already building jdk, you're right, I'll check if I can modify the debug builds to fix this issue

[babaissarkar]

@Stefterv I'm using x86_64 arch.

[babaissarkar]

Slightly offtopic, but related to building:
I do not understand the latter part of this line from BUILD.md, fully

The main task to run or debug the PDE is app:run this run the application with compose desktop

A typo might have crept in unintentionally somewhere (a missing or?).
(I understand the first part of that line however.)

[Stefterv]

This writing was based on the way it is visible within Intellij IDEA, under the ground compose desktop

[SableRaf]

Thanks for catching that. Stef and I made some edits to BUILD.md to improve clarity in #989
