io.github.dropwizard-jobs的Maven依赖项

Question

我正在使用io.github.dropwizard-jobs(https://github.com/dropwizard-jobs/dropwizard-jobs)用于Dropwizard项目中的调度程序。

POM依赖性添加

<dependency>
<groupId>io.github.dropwizard-jobs</groupId>
<artifactId>dropwizard-jobs-guice</artifactId>
<version>4.0.0-RELEASE</version>
</dependency>

集成通过eclipse在本地运行良好，但当尝试使用mvn clean package创建包时，会出现以下错误。

[WARNING]

请让我知道我缺少什么或还需要添加什么。

在POM中，依赖收敛规则是活动的。这意味着，如果在依赖关系树中具有相同依赖关系的不同版本，则构建将失败。

您需要通过添加一个<dependencyManagement>条目来修复com.mchange:c3p0的版本。
