unable to build maven project due to javadoc error?

问题

has anyone come across a simlar maven error 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

回答1:

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

You have three choices:

Fix the errors
disable the strict checking
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

With maven-javadoc-plugin version 3.0.0 <additionalparam/> has been replaced by <additionalOptions/>. To reduce the errors to warnings this pom.xml entry worked for me:

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-javadoc-plugin</artifactId>
            <executions>
                <execution>
                    <id>attach-javadocs</id>
                    <goals>
                        <goal>jar</goal>
                    </goals>
                </execution>
            </executions>
            <configuration>
                <additionalOptions>
                    <additionalOption>-Xdoclint:none</additionalOption>
                </additionalOptions>
            </configuration>
        </plugin>
    </plugins>
</build>

Just update your pom.xml with the properties tag, given below.

<properties>
    <additionalparam>-Xdoclint:none</additionalparam>
</properties>
