Question

我的電腦上安裝了OpenJDK 9，我試圖安裝Eclipse。然而，每次我得到一個錯誤，我啓動安裝程序：

然後，它給我的選項更新：

This is an emergency update: Contiune?

單擊是後，出現此錯誤：

最後，顯示此消息s：

有什麼辦法解決這個問題，我可以安裝eclipse嗎？

Answer 1

瞭解如何configure Eclipse (Installer) for Java 9或download an Eclipse package，而不是直接使用Eclipse的安裝程序。

Answer 2

我一直在與一個非常類似的問題掙扎，並找到了解決方案（您的問題有同樣的原因，可以用相同的方法修復）。與JDK 9在Ubuntu 17.04安裝Eclipse之後，我得到了在啓動時出現以下錯誤：與Eclipse工作時

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

以後可以得到相關的錯誤：Loading available Gradle versions has encountered a problem和Details按鈕顯示此錯誤。

正如我在looking very similar problem in docker之後發現的，問題出在Ubuntu 17.04 JDK安裝（build 9-Ubuntu + 0-9b161-1），其中沒有/conf目錄。這應該在Ubuntu 17.10中更新的JDK版本中修復。

到目前爲止，您有2個選項來解決這個自己：

1. （簡單的方法，假貨conf目錄用符號鏈接）：內JDK創建符號鏈接9目錄（對我來說是/usr/lib/jvm/default-java）用下面的命令： sudo ln -sn lib conf 由於安全策略文件位於/ lib下，因此解決了此問題。

2. （更復雜，通過在適當/ conf目錄中安裝替代JDK來解決問題）：從Oracle下載JDK 9並安裝到某個任意文件夾;然後將此文件夾添加到PATH（例如在.bashrc中）;然後更改JAVA_HOME到這個文件夾中的/ etc /環境
