Build Exceptions

[MatthewDynamic]

I am attempting to build from source (using branch master) following the directions located here: https://github.com/cqframework/clinical_quality_language/blob/master/Src/java/README.md

But I am receiving the following exception:

>> gradlew build
> Task :buildSrc:compileJava FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':buildSrc:compileJava'.
> Could not resolve all files for configuration ':buildSrc:compileClasspath'.
   > Could not resolve com.diffplug.spotless:spotless-plugin-gradle:6.23.3.

The consumer was configured to find a library for use during compile-time, compatible with Java 8, preferably not packaged as a jar, preferably optimized for standard JVMs, and its dependencies declared externally, as well as attribute 'org.gradle.plugin.api-version' with value '8.5' but:

According to README, JDK 1.8 should be used. My path and javahome env varaible are set so that java -version is responding:

java version "1.8.0_391"
Java(TM) SE Runtime Environment (build 1.8.0_391-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.391-b13, mixed mode)

gradlew :cql-to-elm-cli:run produces similar errors.

I do not know enough about gradle or the java ecosystem to do very much debugging. But I believe I have followed the directions clearly. Am I on the correct branch?

Any advice would be greatly appreciated.

Thank you, Matthew Dugal

Readme out of date, a recent JDK is required. Currently targeting JDK 11, expected to move to JDK 17 in August of 2024.

Readme updated to specify 11.

[MatthewDynamic]

I tried multiple versions and got various errors I was not able to figure out. But I did not try 11. Thank you for the update.

If that doesn't work out for you let me know and we'll reopen the issue. :)
