然后它让我可以选择更新：

这是一个紧急更新：继续？

点击yes后出现这个错误：

最后，出现这条消息：

有什么办法可以解决这个问题，以便我可以安装 eclipse？

Answer 1

我正在努力解决一个非常相似的问题并找到了解决方案（您的问题有相同的原因，可以通过相同的方式解决）。在带有 JDK 9 的 Ubuntu 17.04 上安装 Eclipse 后，启动时出现以下错误：Loading available Gradle versions has encountered a problem 和 Details 按钮显示此错误：

An internal error occurred during: "Loading available Gradle versions".
Could not initialize class sun.security.ssl.SSLContextImpl$DefaultSSLContext

稍后您在使用 Eclipse 时可能会遇到相关错误。

我在looking very similar problem in docker 之后发现，问题出在没有/conf 目录的Ubuntu 17.04 JDK 安装（build 9-Ubuntu+0-9b161-1）中。这应该在 Ubuntu 17.10 的较新 JDK 版本中得到修复。

到目前为止，您有 2 个选项可以自行解决此问题：

1. （简单的方法，用符号链接伪造conf 目录）：使用以下命令在JDK 9 目录中创建符号链接（对我来说是/usr/lib/jvm/default-java）：sudo ln -sn lib conf 由于安全策略文件位于 /lib 下，因此可以解决问题。

2. （更复杂，通过安装带有适当 /conf 目录的替代 JDK 来解决问题）：从 Oracle 下载 JDK 9 并安装到任意文件夹中；然后将此文件夹添加到 PATH（例如在 .bashrc 中）；然后将 JAVA_HOME 更改为 /etc/environment 中的此文件夹

Answer 2

了解如何直接configure Eclipse (Installer) for Java 9 或 download an Eclipse package 而不是使用 Eclipse 安装程序。
