Dear Gradle, Why So Stubborn?
Do I do something wrong?
Watching juniors try to set up a project and being greeted by cryptic stack traces like it's some kind of initiation ritual.
`Unsupported class file major version 61`
`invalid CEN header zip64 no access package`, ...
Java can compile code for older versions just fine.
It's literally designed for that.
Oh why, must Gradle behave like a bitter librarian who refuses to hand over a book unless I whisper the exact Dewey Decimal Code?
Every other Language will laugh again at java, seeing this.
💡 Why is Gradle bound to a java version? And if Gradle knows it needs Java 11… why doesn't it just do this for me?
Like using `/usr/libexec/java_home -v 11` in background?
🤖 Is there a clean way to force Gradle into submission without adding another tool like SDKMAN or jabba or YunaBraska/gradle-java-fix or whatever the trendy painkiller of the week is?

@ow2 has quietly released ASM 9.8 here: https://asm.ow2.io/versions.html. This version of the #bytecode manipulation library now support the EA versions of #JDK25. Ok @ApacheGroovy and @rafaelcodes (aka Mr #ByteBuddy) ... you know what to do. #Java #JDK #OpenJDK #OpenSource
Java's Path is 🤦♀️ . Every time I start hammering my forehead on the table.
- javadoc: "A Path is considered to be an empty path ..." but no isEmpty()
- Path.of("a/b").toAbsolutePath() -> "/home/bobo/workspace/a/b". That's somewhat OK, but there is no method "justMakeThisAbsolute()" to get "/a/b". Having the absolute feature in the same class looks like a massive design fail anyway.
- Path.of("a/b").startsWith(Path.of("")) -> false. WOW
The last is my today's favorite.
