执行附加-目标org.apache.maven.plugins:maven-javadoc-plugin:3.0.0:jar的javadocs在Java10中失败
提问于 2018-03-24 02:55:48
在链接升级到Java 10中断Javadoc注释到JDK包的链接之后，尝试复制相同的内容，而我可以将构建配置设置为：
<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>Java mvn clean verify -X. --这在Java-9中成功地用于执行
另一方面，如果我将源和目标更改为10(Java-10)，则由PluginExecutionException引发的具有以下堆栈跟踪的NullPointerException会导致构建失败：

at org.apache.commons.lang3.SystemUtils.isJavaVersionAtLeast (SystemUtils.java:1626)Javadoc插件与Java-10不兼容吗？还是我漏掉了什么配置？

这个问题与“公-朗”杂志有关，它导致了问题，正如您在堆栈跟踪中所看到的那样。
这已在当前的maven-javadoc-plugin发展状况中得到修正。这个需要发布。

解决办法是添加
<configuration>
<failOnError>false</failOnError>
</configuration>到pom.xml中的maven-javadoc插件部分。
