编译/实现anthoer项目时无法执行bootJar任务

Question

执行bootJar或run时发生了什么：

> Task :common:compileJava
> Task :common:processResources NO-SOURCE
> Task :common:classes
> Task :common:jar SKIPPED

> Task :api:compileJava FAILED
D:\workspace\IDEA\bootar\api\src\main\java\com\sample\Application.java:3:
 ����: �����com.sample.common������// looks like package or class not found.
import com.sample.common.CommonClazz;
                        ^
D:\workspace\IDEA\bootar\api\src\main\java\com\sample\Application.java:23:

实际上，项目本身非常简单：

和gradle文件：

IDE可以找到CommonClazz并将其导入Application，但是当我尝试运行或构建api模块时，它失败了。
