+```
+解决IDEA中打包时报：Could not transfer artifact org.pentaho:pentaho-aggdesigner-algorithm:pom:5.1.5-jhyde问题
+```
+解决方法：
+在maven下的setting.xml文件中加入下面的镜像配置内容
+```
+<mirror>
+	<id>alimaven</id>
+	<name>aliyun maven</name> 
+	<url>http://maven.aliyun.com/nexus/content/groups/public/</url>
+	<mirrorOf>central</mirrorOf>

+	<mirrorOf>*</mirrorOf>
+	<name>spring-plugin</name>
+	<url>https://maven.aliyun.com/repository/spring-plugin</url>
+</mirror>
+```
+最后再进行编译`mvn clean instanll -Dmaven.test.skip -U`
