I installed AST view Plugin from Eclipse Market Place. I want to use to show the nodes of a java file abstract syntax tree. However, as in the screenshot, it doesn't go beyond Compilation unit node and says : unsupported JLS. I tried switching JLS versions with the right bar. But it keeps showing the same error.
i installed the AST view plugin manually in the folder plug-in as demonstrated in their website. I also added manually the asked the jdt.core jar in my project and it fixed the problem. I work with eclipse latest version.
