我有一个在本地构建的基于微服务的应用程序。我遇到的情况是,微服务A依赖于微服务B,因此我将B作为依赖项包含在A的pom中,并且代码中没有错误,并且所有类都可以识别。但是,当我在A上执行“ mvn clean install”命令时,出现错误,无法识别B中的所有软件包,并且我尝试从B中的所有类都找到“找不到符号”在A中使用。
我尝试将Maven插件的执行目标更改为B的pom中的“重新打包”,例如:
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<executions>
<execution>
<goals>
<goal>repackage</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
我还已经确认JAR文件已正确构建到.m2文件夹中的本地maven存储库中,并确保其中包含了类和代码。
我还尝试将maven命令分解为子命令,而不仅仅是进行maven全新安装

答案 0 :(得分:0)
如果您的两个微服务都需要一组类,请将这些类放入一个单独的(第三个)jar中,将其构建为普通jar并将其用作两者中的依赖项。
