org/sonar/api/utils/SonarException：不支持的major.minor版本51.0

Question

從3.3.2升級到Sonarqube 5.1.2後，我需要用jdk 1.6構建的項目的maven版本失敗：

似乎是一個兼容性問題，任何想法？ 指向老聲納它仍然正常工作，指向新的聲納，我明白了。

感謝， 羅伯託

Answer 1

運行分析正如你可以在"Requirements" page或"SonarQube 5.0 Upgrade Guide"閱讀，你至少需要Java 7的運行SonarQube分析。

您可以隨時使用Java 6構建（編譯，測試等）您的項目，但是您需要配置SonarQube分析以使用Java 7或更高版本。

Answer 2

SonarQube 5.x的需要Java 7運行服務器和運行分析。

它仍然會分析項目建設與Java 6，但你應該使用Java 7

Answer 3

我陷入了幾乎同樣的問題，通過maven對Jenkins運行我的Sonar分析。在某些時候，得到成功的項目分析開始失敗而：

• SonarQube服務器並沒有改變（版本4.5.6）
• 詹金斯工作的配置並沒有改變（Maven的工作配置了JDK 1.7.0.45）
• Maven的配置並沒有改變

這是我得到：

的ISSU e爲通過之間的Java版本不匹配造成這裏：

• 詹金斯工作與JDK 1.7.x
• 聲納的Maven插件版本3.1.1正在與JDK 1.8.x的編譯執行

插件的版本沒有在pom.xml中顯式設置，所以當作業使用此版本的插件時分析開始失敗。

由於很多原因，作業JDK無法升級到1.8，所以sonar-maven-plugin的版本被固定爲3.0.2。

Answer 4

這是正確的，您需要java 1.7版本。確保你已經更新了jdk版本，而不是jre。

首先驗證用於拾取jdk版本的env變量。

javac -version

輸出：

Picked up _JAVA_OPTIONS: -Xmx512M javac 1.7.0_80

轉到命令行，並按照下面的變化。

Set JAVA_OPTIONS=C:\Program Files\Java\jdk1.7.0_80

或

Set JAVA_HOME=C:\Program Files\Java\jdk1.7.0_80 set PATH=%JAVA_HOME%\bin;%PATH%
