FtrlFM 在用2.2.0和2.1.0编译时有一些问题

我在pom里加入了

>

com.tencent.angel
spark-on-angel-core
${angel.version}
provided

>

com.tencent.angel
spark-on-angel-mllib
${angel.version}
provided

当我${angel.version}，填2.1.0的时候，编译通过，但FtrlFM.class里不存在load函数和save函数，导致没法运行FtrlFMExample.scala；
而当我${angel.version}，填2.2.0的时候，则无法编译通过，报错：
