Help in building jar file of RapidMiner

ajrisalvador

Good day, I'm a relatively new to Java, git, and Gradle. I want to use RapidMiner in Netbeans for a Thesis Prototype.

When I try to build the jar file of RapidMiner, I get this error:

<div>C:\rapidminer-studio-core>gradlew jar

What I've tried so far:

• Edit the gradle-wrapper.properties and set distributionUrl=https\://services.gradle.org/distributions/gradle-5.3-all.zip
• Downgrade to JDK 1.8

Immediate help is needed. Thanks!

I solved it by:

Downgrading to JDK 1.8
AND
Edit the gradle-wrapper.properties and set distributionUrl=https\://services.gradle.org/distributions/gradle-4.0.1-bin.zip
