SonarLint cannot connect to SonarQube Server

Question

I have eclipse mars2 with sonarLint 2.1. I try to connect to a SonarQube Server 5.1.2

When I try to connect via the eclipse GUI, the following error occurs:

The following plugins do not meet the required minimum versions, please upgrade them: java (installed: 3.0, minimum: 3.8)

Do you have any ideas? Thank you guys!

Solution 1

The plugin the message is referring to is the Sonar Java Plugin. Log in to Sonar as admin, go to Administration/System/Update Center and you'll see that the current installed plugin version is 3.0. Update it to the newest version available and it should work.

[Edit] - The upgrade is triggered by just clicking the button, but after it is downloaded and installed, you'll have to restart the Sonar server.

Solution 2

Another option is to downgrade to an older version of the plugin:

1. Exit IntelliJ
2. Delete the files in the following folder (your version of Idea may be in a slightly different folder C:\Users\USER.IdeaIC2018.1\config\plugins\SonarLint\lib
3. Download version 3.5.1.2759 from the following: https://plugins.jetbrains.com/plugin/7973-sonarlint
4. Unzip all the files from the downloaded file to the above folder

Why would someone upgrade it from 3.0 to 3.8 instead of the newest 3.14? Please note that the current version is 3.14, not the same as 3.1.4 (3.14 > 3.8 while 3.1.4 < 3.8). For more informations about the versions check docs.sonarqube.org/display/PLUG/Java+Plugin (clicking on the "More versions" button).

Because I had another plugin not compatible with the newest version of the Java plugin. All sorted now, thank you!

Manual update is also possible docs.sonarqube.org/display/SONAR/Installing+a+Plugin

This question is about the Eclipse plugin, not IntelliJ.
