就我的经验来说，我无法scala-swing.jar在 Ubuntu 存储库的任何地方找到包含该文件的包。我尝试了以下方法：
sudo apt update
apt search scala-swing
apt search scala | grep -i swing
apt-file update
apt-file search scala-swing.jar
apt-file search scala | grep -i swing
我已正确安装了scala和scala-library软件包，但它们都不包含scala-swing.jar:(
# dpkg -L scala

显然，回来在 Ubuntu 14.04 LTS 中，该文件存在在 scala-library` 包中，但是不再是 16.04:( 安装这个文件的正确方法是什么？
答案1
Ubuntu Xenial (16.04) 中没有软件包提供scala-swing.jar文件。但是，如果你真的需要，你可以从java2s 网站。
