Project is based on MAVEN management, has been packaged all right, today packaging inexplicable a lot of mistakes

Did not study for a long time, and finally tried a number of commands, such as: Pakage, test and other commands are not error, only when using install error. Look closely at the log, the final suspicion is in the generation of Javadoc when the error, and try install-d maven.javadoc.skip=true command to skip the generation Javadoc part, sure enough no error.

Careful study of the next, the original Maven Javadoc plugin version of the problem, resulting in the time to generate this error. Increase in POM
