With JAVA_HOME setup to JDK8, errors on modules must not happen
Expected Behavior
With JAVA_HOME setup to JDK8, I should not see errors like "Unable to make protected java.lang.Package[] java.lang.ClassLoader.getPackages() accessible: module java.base does not "opens java.lang" to unnamed module @3f7ff9d9" since the concept of module was introduced in JDK9.
Current Behavior
Could not create an instance of Tooling API implementation using the specified Gradle installation 'C:\Users\nicol\Downloads\gradle-2.3-all\gradle-2.3'. Could not create an implementation of service 'org.gradle.tooling.internal.protocol.ConnectionVersion4'. Could not create an instance of type org.gradle.tooling.internal.provider.DefaultConnection. Unable to make protected java.lang.Package[] java.lang.ClassLoader.getPackages() accessible: module java.base does not "opens java.lang" to unnamed module @3f7ff9d9
org.gradle.tooling.GradleConnectionException: Could not create an instance of Tooling API implementation using the specified Gradle installation 'C:\Users\nicol\Downloads\gradle-2.3-all\gradle-2.3'.

Context
Trying to setup my Eclipse workspace with JDK8 and gradle 2.3.
Steps to Reproduce
Create a test project in Eclipse workspace with JDK8 and gradle 2.3 (screenshot below)
Create build.gradle
plugins {
id 'java'
}
repositories {
mavenCentral()
}
dependencies {
testCompile 'junit:junit:4.13.2'
}
Create Test.java in src/test/java
public class Test {
@org.junit.Test
public void testDummy() throws Exception {
org.junit.Assert.assertTrue(false);
}
}
It works well with the command line gradle build
Your Environment
Buildship: Eclipse Plug-ins for Gradle 3.1.5.v20210113-0929 Eclipse IDE for Java Developers 4.22.0.20211202-1200 JAVA_HOME=C:\jdk1.8.0_311 GRADLE_HOME=C:\Users\nicol\Downloads\gradle-2.3-all\gradle-2.3 PATH=%JAVA_HOME%\bin;%GRADLE_HOME%\bin;%PATH%
I guess this due to the embedded JDK of Eclipse because I can't see what other JDK could have been introduced. I've added this at the end of my eclipse.ini :
--add-opens=java.base/java.lang=ALL-UNNAMED
--add-opens=java.base/java.io=ALL-UNNAMED
--add-opens=java.base/java.util=ALL-UNNAMED
Now I have another error message:
Support for builds using Gradle versions older than 2.6 was removed in tooling API version 5.0. You are currently using Gradle version 2.3. You should upgrade your Gradle build to use Gradle 2.6 or later.
So I assume it means 2.6 is supported ? I will try with 2.6.
So ok, it works with gradle 2.6 and the --add-opens listed above in the eclipse.ini.
But the fact that the embedded JDK of Eclipse interferes with the build is rather upsetting.
Any possibility to fix that by using the configured Java Home from the preferences instead ?
