Use SpongeGradle plugin with Eclipse

Plugins Plugin Development
1

Hi!

I don’t understand how I’ve to use gradle with Eclipse in order to be able to use the Sponge API. It is said that it is recommended to use the SpongeGradle plugin. But I don’t know how to use this with my IDE (Eclipse) and I don’t find any video or blog using it… Can somebody show me how to use this?

Thanks a lot :stuck_out_tongue: (I’m not familiar with Gradle)

EDIT: I was using Maven but I got this error

static interface method invocations are not supported in -source 1.5
[ERROR] (use -source 8 or higher to enable static interface method invocations)

using maven. The code of the class is:.

Hi it’s me again but I decided to create a new account (old e-mail, new username etc… the previous one was too old and I don’t like MrAlexan14’s name anymore)

Indeed the solution is obvious… Just write these lines as mentioned in the doc to the build.gradle file…

plugins {
    id 'java-library'
    id 'org.spongepowered.plugin' version '0.9.0'
}

It has to be at the very beginning of the file if I understood well. Here is my complete file:

plugins {
    id 'java-library'
    id 'org.spongepowered.plugin' version '0.9.0'
}

group = 'io.github.AlexandreGerault.BattleRoyal' // TODO
version = '1.0-SNAPSHOT'
description = 'A battle royal plugin'

dependencies {
    api 'org.apache.commons:commons-math3:3.6.1'
    implementation 'com.google.guava:guava:23.0'
    testImplementation 'junit:junit:4.12'
    compile 'org.spongepowered:spongeapi:7.1.0'
}

repositories {
    jcenter()
}
