myeclipse+maven ,jar包下载的版本问题

在myeclipse中执行maven install的时候,默认下载maven-jar-plugin-2.4.jar的jar包(不能成功下载),但是本地仓库中已经有了maven-jar-plugin的jar包,但是版本是2.3.1,还有许多其他jar包都有这种版本不对应的情况
我知道这个可以在pom中配置插件版本,但我不能一个个去配置啊
额,之前更换了maven和jdk的版本,我想是不是哪里配置不对了?菜鸟求好心人搭救,感谢!
另外补充一点,maven从3.3.3到3.2.1,我直接copy3.3.3的setting到3.2.1目录下,maven的jar版本是和setting有关吗???

首先setting是可以的,

另外,版本的问题确实需要一个一个配置,你可以用property的方式去统一配置版本,

给你个参考:

统一定义版本:
 <properties>
    <maven.compiler.source>1.7</maven.compiler.source>
    <maven.compiler.target>1.7</maven.compiler.target>
     <testversion>1.7</testversion>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
  </properties> 

在引入的地方,使用如下:

 <dependencies>
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>${testversion}</version>
    </dependency>
  </dependencies>

properties块的顺序,记得按照下面这个来:

<project xmlns="http://maven.apache.org/POM/4.0.0"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0
                      http://maven.apache.org/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0</modelVersion>
