[英]Spring boot core dependencies seen as unused by maven-dependency-plugin
maven-dependency-plugin
檢測到 spring 引導依賴項未使用,但實際上需要它們才能運行我的應用程序。 我會做錯什么嗎?

如果要將這些依賴項標記為已使用。
編輯你的pom.xml,如下所示
<plugin>

<version>2.10</version>
<executions>
<execution>
<id>analyze</id>
<goals>

<usedDependency>org.springframework.cloud:spring-cloud-starter-eureka</usedDependency>

</plugin>
@Kerem 答案的增強功能是一次排除所有 spring 依賴項(使用正則表達式),而不是將它們一一列出,這需要未來注意未使用/使用的依賴項。
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<version>${maven-dependency-plugin.version}</version>
<executions>
<execution>
<id>analyze-dependencies</id>
<goals>
<goal>analyze-only</goal>
</goals>
<configuration>
<failOnWarning>true</failOnWarning>
<ignoredUnusedDeclaredDependencies>
<!-- Because of SpringBoot auto-configurations, the configuration is happening outside of your application code, so Maven believes these dependencies to be unused -->
<!-- Static code analysis tools like (maven-dependency-plugin) can not detect runtime dependencies, so you should instruct them about runtime dependencies -->
<!-- https://stackoverflow.com/questions/37528928/spring-boot-core-dependencies-seen-as-unused-by-maven-dependency-plugin -->
<ignoredUnusedDeclaredDependency>org.springframework*:*</ignoredUnusedDeclaredDependency>

</configuration>
</execution>
</executions>
這是正常的,因為您的代碼不直接利用任何這些依賴項。 Spring Boot的工作方式是分析你的類路徑,並通過添加相應的依賴項為你自動配置許多不同的東西。 由於配置發生在應用程序代碼之外,因此Maven認為這些依賴項未被使用。
