The build worked using Docker as you recommended. FYI, for the fun of it, I also installed Java 11 on my Mac and tried to compile without Docker, but the build failed. james-project$ java -version openjdk version "11.0.7" 2020-04-14 OpenJDK Runtime Environment AdoptOpenJDK (build 11.0.7+10) OpenJDK 64-Bit Server VM AdoptOpenJDK (build 11.0.7+10, mixed mode) [INFO] Apache James :: Server :: Task :: Memory implementation FAILURE [ 40.001 s] [ERROR] Tests run: 32, Failures: 0, Errors: 32, Skipped: 0, Time elapsed: 0.089 s <<< FAILURE! - in org.apache.james.task.MemoryTaskManagerTest [ERROR] additionalInformationShouldBeUpdatedWhenFailed Time elapsed: 0.018 s <<< ERROR! java.lang.NoSuchMethodError: 'void org.apache.james.task.MemoryTaskManager.<init>(org.apache.james.task.Hostname)' at org.apache.james.task.MemoryTaskManagerTest.setUp(MemoryTaskManagerTest.java:33) [ERROR] getStatusShouldReturnCompletedWhenRunSuccessfully Time elapsed: 0 s <<< ERROR! java.lang.NoSuchMethodError: 'void org.apache.james.task.MemoryTaskManager.<init>(org.apache.james.task.Hostname)' at org.apache.james.task.MemoryTaskManagerTest.setUp(MemoryTaskManagerTest.java:33) Should I file a bug?
