I'm trying to build a legacy Grails 2.3.11 application but I get error messages like this:

| Error Resolve error obtaining dependencies: Failed to read artifact descriptor for javax.servlet:javax.servlet-api:jar:3.0.1 (Use --stacktrace to see the full trace)
| Error Failed to read artifact descriptor for javax.servlet:javax.servlet-api:jar:3.0.1
| Run 'grails dependency-report' for further information.
