Question

当我尝试构建应用程序时，由于我是Maven的新手，所以我遇到以下错误：我不完全了解导致构建失败的问题所在。

以下是针对构建失败而打印的日志消息：

请告诉我是否需要其他详细信息。

使用的Ant版本：apache-ant-1.10.3

使用的Maven版本：apache-maven-3.2.1

在构建失败的子Pom上执行编辑：

依赖性管理标记之间的是：

Answer 1

您（或您的父POM）激活了依赖性收敛实施器规则。如果在传递依赖关系树中具有相同工件的不同版本，则此规则将使构建失败。

通过将适当的条目添加到POM的<dependencyManagement>部分中（对于具有不同条目的工件），可以停用执行者规则或解决收敛问题。

org.apache.ant：ant-launcher：1.8.2
