----------------------------------

             Summary: The curl command in sbt-launch-lib.bash doesn't download sbt-launch jar
                 Key: SPARK-9341
                 URL: https://issues.apache.org/jira/browse/SPARK-9341
             Project: Spark
          Issue Type: Improvement
          Components: Build
    Affects Versions: 1.4.1
         Environment: Ubuntu 13.10
            Reporter: Vishal John
            Priority: Minor


I try to build spark by using the command ./build/sbt 

I get the following error -
Attempting to fetch sbt
Launching sbt from build/sbt-launch-0.13.7.jar
Error: Invalid or corrupt jarfile build/sbt-launch-0.13.7.jar

I debugged and found out that URL1 repo is outdated. So it's giving 404. The problem I found with the curl script is that it didn't tried the URL2

Also the ULR2 is now being redirected. So the curl command should have -L option to follow redirect.

Once I changed like this - (curl --silent -L ${URL2} > "${JAR_DL}" || curl --silent ${URL1}  , it worked for me.

To fix:
1. curl should try URL2 if URL1 is not working
2. use -L option in curl to follow rediect
