FAILURE: gradle clean install or ./gradlew clean install

[RLWOHIO]

Hi,

I am unable to install GroBid with my local gradle (8.3 or 8.9) or the gradlew wrapper included in the grobid download. My system: HPC Linux cluster (4.18.0-553.8.1.el8_10.x86_64), JDK 20. Below are the errors. Please see details in the attached log files. I looked through the previous issues with regard to installation and did't get much help from the discussions therein. Thanks much for your help!

Before creating a new issue, make sure you had a look at the official documentation. For specific questions, you can try the Mendable Q/A chat (NOTE: This is rather experimental, if not sure, make sure you double-check using the official documentation.)

• What is your OS and architecture? Windows is not supported and Mac OS arm64 is experimentally supported. For non-supported OS, you can use Docker (https://grobid.readthedocs.io/en/latest/Grobid-docker/)

• What is your Java version (java --version)?

• In case of build or run errors, please submit the error while running gradlew with --stacktrace and --info for better log traces (e.g. ./gradlew run --stacktrace --info) or attach the log file logs/grobid-service.log or the console log.

Hello @RLWOHIO !

I think gradle 7.2 is not compatible with JDK 20 - thus the error "Unsupported class file major version 64".
To solve the issue, you can use JDK 17 for building the project.

(the Grobid gradle wrapper uses the version of gradle indicated under gradle/wrapper/gradle-wrapper.properties, the version of Jacoco currently used in build.gradle is also not compatible with gradle >=8, so we will need some updates in the future to support Gradle 8).

Thanks so much @kermitt2 ! The included gradle 7.2 does indeed require JDK 17. The build was successful! I have been warned by my admin though that JDK 17 is outdated and may pose security risks. Hopefully GroBid will update to newer versions of gradle and JDK soon.
