作为Maven小白,今天这问题困扰了我好久,经过多次在网上查询,终于找到了原因。明明一个小问题却耗费很多时间,着实不应该,所以必须记录一下。
报错信息如下:

原因:
提取错误的关键信息
说明Jar包出现了问题。
那么接下来就要找哪个jar包出现了问题:
方法1、可通过右击项目名 -> Run as -> Maven test ,这时控制台会报哪个jar包出错。 (也可以打开DOS命令窗口,切换至项目目录,运行mvn test命令,和Eclipse的控制台输出信息一致)
方法2、如果方法1未出现任何错误信息,那么就使用笨办法。打开项目中的pom.xml文件,在自己的Maven本地仓库去查找pom.xml文件中每一个dependency节点所对应的jar包版本。一个一个对比,看看是否都正常下载。
这里,我找到了本地仓库中出现的jar包错误:
解决方法:
既然jar包未下载成功,那么重新下载就行了。如果重新下载还是不能成功,那就在网上下载同版本的拷贝进去。
删除掉该jar包所在目录下的所有文件后,重新运行maven install。
这时,可看到jar包已正常下载。
再次运行项目,右击项目 -> Run as -> Run on server 。可以发现,项目能正常运行了。
