maven - Load data from redshift using spark-redshift in Java -

i trying load data redshift in spark using spark-redshift in java.

//dataframe iplocation = sqlcontext.read().schema(customschema).json(jsonfile.getfile().getpath());          dataframe iplocation = sqlcontext.read()                     .format("com.databricks.spark.redshift")                     .option("url", "jdbc:redshift://test.us-east-1.redshift.amazonaws.com:5439/spay?user=&password=")                     .option("query", "select * test.iplocation")                     .option("tempdir", "s3n://test/")                     .load(); 

pom dependecies added

<dependency>     <groupid>org.apache.spark</groupid>     <artifactid>spark-core_2.10</artifactid>     <version>1.6.1</version>     <!-- <scope>provided</scope> --> </dependency> <dependency>     <groupid>org.apache.spark</groupid>     <artifactid>spark-streaming_2.10</artifactid>     <version>1.6.1</version>     <!-- <scope>provided</scope> --> </dependency> <dependency>     <groupid>org.apache.spark</groupid>     <artifactid>spark-sql_2.10</artifactid>     <version>1.6.1</version> </dependency> <!-- https://mvnrepository.com/artifact/com.databricks/spark-redshift_2.10 --> <dependency>     <groupid>com.databricks</groupid>     <artifactid>spark-redshift_2.10</artifactid>     <version>0.6.0</version> </dependency> 

i getting following error

java.lang.reflect.invocationtargetexception             @ sun.reflect.nativemethodaccessorimpl.invoke0(native method)             @ sun.reflect.nativemethodaccessorimpl.invoke(nativemethodaccessorimpl.java:62)             @ sun.reflect.delegatingmethodaccessorimpl.invoke(delegatingmethodaccessorimpl.java:43)             @ java.lang.reflect.method.invoke(method.java:498)             @ com.databricks.spark.redshift.jdbcwrapper.registerdriver(redshiftjdbcwrapper.scala:59)             @ com.databricks.spark.redshift.redshiftrelation.schema(redshiftrelation.scala:56)             @ org.apache.spark.sql.execution.datasources.logicalrelation.<init>(logicalrelation.scala:37)             @ org.apache.spark.sql.dataframereader.load(dataframereader.scala:125)             @ com.samsung.cloud.mopay.trsanalytics.test.etl.spark.testsparkposttoken.testspark(testsparkposttoken.java:69) 

am missing dependencies here? spark-redshift support java? using wrong version here ?
