生成文档的NullPointerException插件

Question

我正在尝试运行maven-enunciate plugin:1.26.2:docs and facing a NUllPointerException。

我唯一想要的就是这里描述的文档生成http://docs.codehaus.org/display/ENUNCIATE/Documentation+Only，所以我的pom.xml是：

...

<plugin>
    <groupId>org.codehaus.enunciate</groupId>
    <artifactId>maven-enunciate-plugin</artifactId>
    <version>1.26.2</version>
            <configuration>
                <docsDir>${project.build.directory}/docs</docsDir>
            </configuration>
            <executions>
                <execution>
                    <goals>
                        <goal>docs</goal>
                    </goals>
                </execution>
            </executions>
</plugin>

...

但是，它启动了：

Caused by: org.apache.maven.plugin.MojoExecutionException: Problem assembling the enunciate app.

有什么建议吗？

Answer 1

尝试版本1.27。如果它仍然发生，打开一个bug。

Answer 2

记录在案。我在使用1.27版本时遇到了这个问题：https://jira.codehaus.org/browse/ENUNCIATE-771，然后我跳到了1.28版本，遇到了上面提到的问题。
