（複製的可能不僅僅是信息更多這是解決這個問題所需要的，但我不知道它需要什麼信息）。

我試圖在互聯網上找到解決方案，但對人們建議的解決方案感到困惑。我在我的電腦上重新安裝了java（到最後一次更新），但沒有任何改變。

請向我解釋如何解決這個問題（如果有什麼我可以做的），因爲我不瞭解人們在互聯網上看到的解決方案中使用的特殊和/或縮短的單詞（如JRE ，我不知道該怎麼做，他們要求做測試。

太感謝你了。

可能的重複http://stackoverflow.com/questions/10382929/unsupported-major-minor-version-51-0 –

不受支持的版本MAJOR.MINOR 51.0表明，所包含的罐子二進制類（又名字節代碼）是爲更新的JRE版本編譯的。

JRE版本docs point s版本，該版本51是JRE 7.

發出命令檢查您的版本。

java -version

JRE 7可能不附帶您的操作系統。所以你可以選擇自己設置JRE（在/ opt中）並使用JAVA_HOME環境變量來使用它。

是......更確切地說，這是字節碼版本。 – fge

「設置JRE 7並重新運行。」我怎麼做？ – user2217286

^^我想過。我不是Mac OS專家。這可能有助於http://www.mkyong.com/java/how-to-set-java_home-environment-variable-on-mac-os-x/ –

你已經編譯了Java 7，而你的服務器只運行Java 6.你可以安裝Java 7，但是使用Bukkit，如果你計劃製作公開的插件，你在網上發佈，我建議只針對Java 6構建很多用戶使用它，Bukkit的開發人員甚至建議這樣做。
