我有一个多模块(模型和服务模块)maven项目:
model
|_____ABCEntity.java
service
|_____pom.xml
<dependency>model</dependency>
<dependency>code-generation</dependency>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>exec-maven-plugin</artifactId>
<configuration<mainClass>com.codegenerator.CodeGeneratorApplication</mainClass></configuration>
</plugin>
在&#34;模型&#34;模块我有一个类名ABCEntity.java,在服务模块中,我想扫描ABCEntity.java并生成一些样板类。
&#34;服务&#34;模块对&#34;模型&#34;具有maven依赖性。模块加上对代码生成器模块的依赖(外部应用程序)。
当我运行&#34; mvn exec:java&#34;在&#34;服务&#34;模块,我收到了一些错误,找不到ABCEntity.java:

... 6 more
Caused by: java.lang.ClassNotFoundException: ABCEntity
有人可以帮我吗?我不明白为什么无法找到ABCEntity,因为: 1)ABCEntity在同一个项目中但在另一个模块中 2)我已经声明了对该模块的依赖。
答案 0 :(得分:0)
似乎一旦我使用了这个插件的另一个目标(我只是执行mvn exec:exec),就可以找到ABCEntity:
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>exec-maven-plugin</artifactId>
<version>1.6.0</version>
<configuration>
<executable>java</executable>
<arguments>
<argument>-classpath</argument>
<!-- automatically creates the classpath using all project dependencies,
also adding the project build directory -->
<classpath />
<argument>codegenerator.CodeGeneratorApplication</argument>
...
</arguments>
</configuration>
</plugin>
但我不确定背后的真正原因。
答案 1 :(得分:-1)
您可以访问this
<executableDependency>
<groupId>your groupId</groupId>
<artifactId>>model</artifactId>
</executableDependency>
<mainClass>com.codegenerator.CodeGeneratorApplication</mainClass>
