我的应用程序无法构建甚至运行。它给我一个创建 CEF 浏览器失败的错误。
直到今天，一切都运行良好。我按照此链接中的说明再次卸载并安装了 CEF:Big Changes and CEF但它仍然给了我错误。
这是控制台中的完整错误:

可能是什么问题呢？

最佳答案

这是一个 known issue现在使用 Linux。

UnsatisfiedLinkException (libjcef.so: libjawt.so)On Ubuntu 20, and some other versions of Linux, it has been reported that, when running the Codename One simulator with CEF installed, you get UnsatisfiedLinkException mentioning that libjcef.so could not find libjawt.so. This is caused because the lib directory of the JDK is not in the LD_LIBRARY_PATH. You an work around this problem by adding it. E.g.

export LD_LIBRARY_PATH=$JAVA_HOME/lib/amd64
