Question

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'并且我出现以下错误

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

你有解决方案吗？

谢谢

Answer 1

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，问题在于：

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

没有artifactId'spring'它应该是spring-core。

Answer 2

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

您必须更改此相关性并将其重命名为spring-core而不是spring

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