1、[ERROR] 'build.resources.resource.directory' 
解决：需要在pom.xml的project->build->resources节点下，加入以下节点：
（解决时，添加了directory节点）

        <resources>

            <resource>

                <directory>src/main/resources</directory>

                <includes>

解决：maven-shade-plugin插件有个配置属性:createDependencyReducedPom,默认值为true。
注意这个属性,如果你用这个插件来deploy,或者发布到中央仓库，这个属性会缩减你的pom文件,会把你依赖的<dependency>干掉。
正确的做法是把这个值改成false，如下：
在project->build->plugins->plugin节点,
<plugin>
