出现错误（使用 java 1.8 构建）
Failed to execute goal org.apache.maven.plugins:maven-javadoc-plugin:2.10.4:jar (attach-javadocs) on project commons-parent: Execution attach-javadocs of goal org.apache.maven.plugins:maven-javadoc-plugin:2.10.4:jar failed: An API incompatibility was encountered while executing org.apache.maven.plugins:maven-javadoc-plugin:2.10.4:jar: java.lang.ExceptionInInitializerError: null
尝试了很多东西都没有用，任何人都可以看看并提供帮助。
首先，尝试升级 maven-javadoc-plugin 版本。
如果不行...
(1) 确保项目构建时没有 maven-javadoc-plugin.
mvn -Dmaven.javadoc.skip=true verify
(2) 禁用严格 linting。
这是版本 3.0.0+。

<artifactId>maven-javadoc-plugin</artifactId>
<version>...</version>
<configuration>
<additionalOptions>

</additionalOptions>
</configuration>
</plugin>
如果 (2) 有效，则很可能是您的 Javadoc 有问题。构建日志中是否有更多信息可以指示位置？

出现错误（使用 java 1.8 构建）
Failed to execute goal org.apache.maven.plugins:maven-javadoc-plugin:2.10.4:jar (attach-javadocs) on project commons-parent: Execution attach-javadocs of goal org.apache.maven.plugins:maven-javadoc-plugin:2.10.4:jar failed: An API incompatibility was encountered while executing org.apache.maven.plugins:maven-javadoc-plugin:2.10.4:jar: java.lang.ExceptionInInitializerError: null
尝试了很多东西都没有用，任何人都可以看看并提供帮助。
首先，尝试升级 maven-javadoc-plugin 版本。
如果不行...
(1) 确保项目构建时没有 maven-javadoc-plugin.
mvn -Dmaven.javadoc.skip=true verify
(2) 禁用严格 linting。
这是版本 3.0.0+。

<additionalOptions>

</additionalOptions>

</plugin>
如果 (2) 有效，则很可能是您的 Javadoc 有问题。构建日志中是否有更多信息可以指示位置？
