目标org.apache.maven.plugins执行attach-javadocs：maven-javadoc-plugin：3.0.0：jar使用Java10失败 [英] Execution attach-javadocs of goal org.apache.maven.plugins:maven-javadoc-plugin:3.0.0:jar failed with Java10

问题描述

点击链接升级到Java 10将Javadoc注释中的链接分解为JDK包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 commons-lang 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 maven -javadoc-插件 。这需要发布。

This has been fixed in current state of development maven-javadoc-plugin. This needs to be released.
