LibGDX无法创建项目

Question

I cannot create a new libgdx project with the gdx-setup.jar. It tells me the BUILD FAILED when I checked advanced > eclipse to use it in eclipse. It tells me the following:

Generating app in D:\programmierung\libgdx\test
Executing 'D:\programmierung\libgdx\test/gradlew.bat clean --no-daemon eclipse afterEclipseImport'
To honour the JVM settings for this build a new JVM will be forked. Please consider using the daemon: https://docs.gradle.org/4.6/userguide/gradle_daemon.html.

How can I fix this?

Answer 1

The problem isn't caused by a wrong libgdx installation.

Please check that C:\\Program Files\\Java\\jre1.8.0_201 contains a valid JDK installation.

Make sure your JAVA_HOME points to a JDK instead of a JRE.

Also, it's a good idea that your JDK are the same version as what declared in the build.gradle found in each submodule (core, desktop, android, ios...). You should find an entry similar to this:

sourceCompatibility = '1.8'

So choose your JDK accordingly.

Answer 2

You seem to be using a JRE for gradle. You need to be using a JDK, it can be downloaded here .
