Subject Warnings when using J11 and groovy3.0.0-alpha-3
Date Wed, 05 Sep 2018 09:27:29 GMT
Hi,
I am using J11 latest Oracle build plus groovy 3.0.0-alpha-3.

The groovy test program is a simple print hello script

I am using Intellij with Gradle and the relevant parts of the build file are:

repositories {
    mavenCentral()
    maven {
        url "https://dl.bintray.com/groovy/maven"
    }
}

dependencies {
    compile 'org.codehaus.groovy:groovy:3.0.0-alpha-3'
    compile group: 'javax.xml.bind', name: 'jaxb-api', version: '2.3.0'
}

The program works but I get a warning as follows:

"C:\Program Files\Java\jdk-11\bin\java.exe" "-Dtools.jar=C:\Program Files\Java\jdk-11\lib\tools.jar"

hello from test

Process finished with exit code 0

Where hello from test is what I was expecting!

Is this currently expected behaviour or is something amiss?

Apache Groovy

Stable: 2.5.2, Preliminary: 3.0.0-alpha-3

For 2.5, Groovy classes compiled with JDK10 should run on JDK11. Groovy 3.0 builds and all
tests pass on JDK11 but further testing is required.

See previous answer.

See previous answer.

2.5.2 was released yesterday. Groovy 3.0.0 final doesn't have a set target date yet but isn't
due in the next few months.
