I also met the same problem today, because the tip before "Error: (8, 13) Java: package javax.mail. The annotation invisible" this Error message, after finding out information on the Internet will change the JDK version 8, in order to appear the Error,
The debug an afternoon feel this package should be an annotation problem, putting the JDK level 9 back, with the method of annotation in the pom with the
