Google Analytics API example JAVA

Google analytics posted on their blog about an example Java program to extract data and output to a CSV using the analytics api, im trying to compile this program to run it in eclipse but running into problems

http://code.google.com/p/ga-api-java-samples/source/browse/trunk/src/v2/DataOverTime/src/example/MainDemo.java

i have changed out the variables in here to my own:

// User configurations.
  private static final String USERNAME = "INSERT_YOUR_GOOGLE_ACCOUNT_LOGIN";
  private static final String PASSWORD = "INSERT_YOUR_GOOGLE_ACCOUNT_PASSWORD";
  private static final String TABLE_ID = "INSERT_YOUR_TABLE_ID";

i'm unsure on the next step, when i try to run the program i get this error message:

    Exception in thread "main" java.lang.Error: Unresolved compilation problem: 

    at MainDemo.main(main.java:51)

update:

ok, its says when using th开发者_Python百科e google analytics API i need to reference some .jar files:

gdata-core-1.0.jar gdata-client-meta-1.0.jar gdata-client-1.0.jar gdata-analytics-meta-2.0.jar gdata-analytics-2.0.jar google-collect-1.0-rc1.jar jsr305.jar

i put these in but its still not working i get the following error message:

Exception in thread "main" java.lang.Error: Unresolved compilation problems: 
    Results cannot be resolved to a type
    The method getData(DataQuery) from the type DataOverTime refers to the missing type Results

Is your directory structure correct? It should look somewhat like the url of the example. The file has to be './example/MainDemo.java' and compile it from '.'

I got the answer in this forum: http://code.google.com/apis/analytics/groups/exportApiGroup.html?place=topic%2Fgoogle-analytics-data-export-api%2FwpDmftjYFio%2Fdiscussion
