'gradlew jar' fails

[Posri]

Greetings Glide,

Sorry for the so basic question, but I followed the README.md to clone the repo, and when I run 'gradlew jar' I get warnings 'can't find referenced class java.lang.Class'.  I have my ANDROID_HOME set correctly (to build our other app).  The build fails with 'Execution failed for task ':annotation:compileJava'.  I have platforms android-30 ... android-33 installed in SDK Manager. 

I just want to run the samples like stated in the README.md.  I must be overlooking something simple, but I can't figure it out. 

Thanks for any tips.  Sincerely,

George

Hi George,

I haven't been building Glide for a while, but as far as I know the annotation module is pure Java, no Android code.

Which JDK are you using? According to CI, it should be 11: https://github.com/bumptech/glide/blob/master/.github/workflows/build.yml#L15

Try setting JAVA_HOME=/path/to/jdk11 before you run the gradlew command.

If it doesn't work, please run `gradlew ...` with `--scan` argument, the "Build scan" link at the end helps to see the full context and error message(s).

Thank you Róbert!  I did specify JAVA_HOME like you said, but it still fails.  Here is the scan report: https://scans.gradle.com/s/rt55ftpggu3t2

Hopefully you see something obvious, I appreciate that you answered !

Sincerely, George

I can't see it, sorry... and when I run that task or `gradlew jar` in general, it "just works". I'll give some info below that might help, but I'm clueless at this at the moment.

The only thing I see different is Windows vs Linux and that you're running a JDK from an Android Studio/IntelliJ IDEA.

I have an older one:

...\java-11.0.2-x64-openjdk\bin>java -version
Picked up JAVA_TOOL_OPTIONS: -Xms32M -Xmx256M -XX:+UseG1GC -D-XX:+PrintCommandLineFlags

OpenJDK Runtime Environment 18.9 (build 11.0.2+9)
OpenJDK 64-Bit Server VM 18.9 (build 11.0.2+9, mixed mode)

When I run with diagnostics on this task: `gradlew :annotation:compiler:proguard --rerun-tasks --info`, I get the below logs.

Try to compare what's different and remedy somehow.

In your 9MB of logs it is missing very basic Java classes like Object and String and List, which is just plain weird. I haven't seen that before in this context. Maybe try with another JDK 11.

Dear Róbert, you are golden, THANK YOU!! 

Your observation, "that you're running a JDK from an Android Studio/IntelliJ IDEA" nailed it. 

I installed openjdk-11 and set my JAVA_HOME accordingly, (I have to have jdk 8, 19 installed also for other projects).  Now it works no issues. 

I appreciate your presence on this project and message board!

Sincerely, George

[Róbert Papp (TWiStErRob)]

Glad to hear it works now! Onwards to hacking the Glide sample :)

> Your observation, "that you're running a JDK from an Android Studio/IntelliJ IDEA" nailed it. 

This is why I asked for the Build Scan, it contains a ton of info, like on the Infrastructure page:

Java runtime

JetBrains s.r.o. OpenJDK Runtime Environment 11.0.13+0-b1751.21-8125866

It's still very weird that the IntelliJ embedded JDK, that is meant for developing Java apps, is not compatible with Java :)

Can you please check from which Android Studio / IDEA version you used the JDK? (I would like to try and reproduce it, and report if possible.)

You can read it from your original (broken) JAVA_HOME=p:\tools\ide\android-studio\jbr and next to the jbr folder there's a build.txt

[Posri]

It is this:

I see it is java 17.  I thought previously it was Java 11.  Nonetheless, I had tried building it in the Android Studio IDE, and it compiled without errors but it wouldn't run on the emulator.  After applying your suggestion to install Java 11, the flickr sample now runs on the emulator.  It is thrilling to see.

Cheers, George
