From 2a2f4e20b413c12a634bb6c3732da4da598bad96 Mon Sep 17 00:00:00 2001 From: Alexander Kriegisch Date: Sat, 20 Mar 2021 14:45:51 +0700 Subject: Fix tests not finding project base directory 'org.aspectj' Several LTW tests using class TestServer failed on my machine because there was a hard-coded project base directory name 'org.aspectj' in the class. This class has several other problems, but my quick fix for now - I did not want to rename my project base directory - was to match on a regex '(?i)(org[.])?aspectj' now. That also works for my root directory 'AspectJ'. I also moved the code determining the project dir into a protected (hence testable) method and added a sanity test case checking if the directory can be determined. If not, the test will fail with a rather lengthy warning to developers about the need to have a matching project root folder.
