Unable to build Maven project due to Javadoc error?

Question

Has anyone come across a similar Maven error as below?

I am unable to build my project due to the error below. All was working previously fine before I started working on the code.

I did not even work on the below defined interfaces and it seems to be related to Javadoc?

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-javadoc-plugin:2.9.1:jar (attach-javadocs) on project jonney-project: MavenReportException: Error while creating archive:

[ERROR] Exit code: 1 - /Users/me/Work/myProject/library/src/main/java/com/me/someInterface.java:45: warning: no @return

I'm guessing you switched to Java 8. In this version Javadoc is stricter on the requirements.

You have three choices:

1. Fix the errors
2. disable the strict checking
3. skip Javadoc when building

To disable the strict checking, add this to your pom.xml

<plugins>
  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-javadoc-plugin</artifactId>
    <configuration>
      <additionalparam>-Xdoclint:none</additionalparam>
    </configuration>
  </plugin>
</plugins>

to skip Javadoc while building, use this:

mvn -Dmaven.javadoc.skip=true verify
