Thymeleaf: "cannot find declaration to go to" error on Intelijj

I am making a project in which I am using Thymeleaf.

IDE is IntelliJ IDEA Community Edition 2020.2 x64.

Intellij cannot recognize Thyemeleaf and I get following message when I am hovering over th:each "Cannot find declaration to go to".

In that file, I put following tag <html lang="en" xmlns="http://www.w3.org/1999/xhtml" xmlns:th="http://thymeleaf.org">.

This is my pom.xml:

Can someone tell me where is the problem?

Solution

  • Thymeleaf is only supported in IntelliJ IDEA Ultimate, not in the community edition. See https://www.jetbrains.com/idea/features/editions_comparison_matrix.html
