我尝试在 Linux 下使用 Eclipse Kepler 在我的 java 项目中运行 javadoc，但收到此错误：
Constructing Javadoc information...

我究竟做错了什么？
尝试添加rt.jar from JAVA_HOME/lib/ 到bootclasspath。例如 ：
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-javadoc-plugin</artifactId>
<version>2.9.1</version>
<configuration>
<minmemory>256m</minmemory>
<maxmemory>1024m</maxmemory>
<!-- error fix -->
<bootclasspath>${java.home}/lib/rt.jar</bootclasspath>
</configuration>
<reportSets>
<reportSet>
<reports>
<report>aggregate</report>
</reports>
</reportSet>
</reportSets>
</plugin>
