maven clean install - 无法在项目 myGoogleAppEngine 上执行目标

我创建了一个 Maven 项目。之前,在我的 pom.xml 中,我使用的是 spring 版本 2.5.6,现在,我将 spring 的版本号更改为使用 3.1.0.RELEASE。

要更新不同的依赖项并更新我的 WEB-INF/lib 中的不同 jar,我使用了以下命令行:'mvn clean install',但出现以下错误

[WARNING] The POM for org.springframework:spring:jar:3.1.0.RELEASE is missing, no dependency information available

原文答案

答案:

如果要升级 Spring 版本,请将其升级到最新的 v3: 3.2.5.RELEASE ,如 Maven mvn 存储库中所述: http://mvnrepository.com/artifact/org.springframework

但是,您的问题在这里:

<dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring</artifactId>
      <version>${org.springframework.version}</version>
 </dependency>

没有 artifactId 'spring' 它应该是 spring-core

没有名为 org.springframework:spring:3.1.0.RELEASE 的依赖关系。此 groupId/artifactId 组合可用的最后一个 jar 用于版本 2.5.6.SEC03

您必须更改此依赖项并将其重命名为 spring-core 而不是 spring

<dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-core</artifactId>
      <version>${org.springframework.version}</version>
</dependency>
