Question

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

Answer 1

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。
