Description: Extensible Tool Platform and Java IDE
 The Eclipse Platform is an open and extensible platform for anything and yet
 nothing in particular. It provides a foundation for constructing and running
 integrated software-development tools. The Eclipse Platform allows tool
 builders to independently develop tools that integrate with other people's
 tools so seamlessly you can't tell where one tool ends and another starts.
 .
 This package provides the whole Eclipse SDK that contains Eclipse Platform,
 Java development tools and Plug-in Development Environment, including source
 and both user and programmer documentation.

Answer 1

我得到了一个错误：

$ sudo snap install eclipse --classic  
error: snap "eclipse" has "install-snap" change in progress

我试了很久才解决这个问题，最后我终于解决了这个问题：

运行命令：

$ snap changes

并检查其输出是否显示“正在执行”，如下所示：

ID   Status  Spawn               Ready  Summary
92   Doing   today at 15:17 IST  -      Install "eclipse" snap

如果是，您只需使用命令就可以中止此操作：

sudo snap abort 92

92是身份证。

然后，如果您再次运行安装命令，它可以正常工作。

sudo snap install eclipse --classic

希望这能帮上忙。

Answer 2

我建议您更加轻松和舒适：

sudo apt --remove purge eclipse

或

sudo apt --remove purge netbeans

并安装SNAP表格：

sudo snap install eclipse --classic

或

sudo snap install netbeans --classic

Answer 3

我建议安装Eclipse包，它也是最新的(面向Java开发人员的Eclipse 4.7.3版)：

sudo snap install eclipse --classic  

您可以在apt包旁边安装snap包，以便尝试它们，然后如果您更喜欢snap包，则可以删除Eclipse包。
