Failure to transfer org.apache.maven.plugins:maven-resources-plugin:jar:2.6

eclipse导入maven项目后pom.xml的报错信息如下：
Failure to transfer org.apache.maven.plugins:maven-resources-plugin:jar:2.6 from https://repo.maven.apache.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced. Original error: Could not transfer artifact org.apache.maven.plugins:maven-resources-plugin:jar:2.6 from/to central (https://repo.maven.apache.org/maven2):
sun.security.validator.ValidatorException: PKIX path building failed:sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

根据提示可知maven依赖下载不完整，所以需要
1、删除原来的 2、重新更新导入
1、在pom.xml加入以下代码

	    <dependency>
    		<groupId>org.apache.maven.plugins</groupId>
    		<artifactId>maven-resources-plugin</artifactId>
    		<version>2.6</version>
		</dependency>

找到路径D:\program\apache-maven-3.8.1\maven-repository\org\apache\maven\plugins\maven-resources-plugin

删掉

2、选中项目–》右击–》Maven–》Update Project–》OK

更新完可看到下载好了，报错提示消失
