Failed to compare ${p1} to ${p2}

Error message

Failed to compare ${p1} to ${p2}

What it means

RuntimeException from MavenProjectBuildFile.isSameFile: Files.isSameFile threw (typically an IOException because one of the two paths does not exist — e.g. an expected pom or catalog file is missing) while comparing two filesystem paths of project files. The two path arguments are interpolated into the message.
