我正在尝试使用这个 tutorial 设置一个带有 eclipse 的 libGdx
但是当我尝试构建项目时出现此错误

Configuration on demand is an incubating feature.

我知道 Maven，但我不知道 gradle，所以即使我做了教程中的所有操作，我也无法理解异常和哪里出错了，请帮忙？

最佳答案

经过大量搜索，我发现我需要将我下载的 GWT 添加到 eclipse 插件中，而这在教程中没有提到

所以我所做的是

in eclipse go to  WINDOWS --->PREFERENCE--->GOOGLE ---->WEB TOOLKIT --->add and search for the folder you have extracted its ZIP file 

关于java - 使用 Eclipse 设置 LibGDX 时出现 Gradle 错误，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/26323772/
