本文介绍了目标org.apache.maven.plugins执行attach-javadocs：maven-javadoc-plugin：3.0.0：jar使用Java10失败的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
点击链接并尝试重现相同内容，同时我可以将构建配置设置为：
Following the link Upgrade to Java 10 breaks links in Javadoc comments to JDK packages and trying to reproduce the same while I could set the build configuration to :
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.7.0</version>
<configuration>
<source>9</source>
<target>9</target>
</configuration>
<dependencies>
<dependency>
<groupId>org.ow2.asm</groupId>
<artifactId>asm</artifactId>
<version>6.1</version>
</dependency>
</dependencies>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-javadoc-plugin</artifactId>
<version>3.0.0</version>
<configuration>
<additionalOptions>
<additionalOption>-html5</additionalOption>
</additionalOptions>
<nodeprecatedlist>true</nodeprecatedlist>
<notree>true</notree>
<quiet>true</quiet>
<show>public</show>
<splitindex>true</splitindex>
</configuration>
<executions>
<execution>
<id>attach-javadocs</id>
<goals>
<goal>jar</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
注意 - 这与Java成功配合使用-9执行 mvn clean verify -X 。
Note - This works successfully with Java-9 on executing mvn clean verify -X.
另一方面，如果我将源和目标更改为10（Java-10），则构建将因 NullPointerException 导致 PluginExecutionException 而失败以下堆栈跟踪：
On the other hand, if I change the source and target to 10(Java-10), the build fails with a PluginExecutionException caused by NullPointerException with following stack trace :

Javadoc插件是不兼容Java- 10？或者我在那里错过了一些配置？
Is the Javadoc plugin not compatible with Java-10? Or am I missing some configuration there?

推荐答案
问题与中的问题导致了问题，你可以在堆栈跟踪中看到。
The problem was related to an issue in commons-lang which caused the issue as you can see in the stack trace.
这已在当前的开发状态中修复。这需要发布。
This has been fixed in current state of development maven-javadoc-plugin. This needs to be released.
