Quickstart: Error downloading spatial library dependency

[Allen Vannoppen]

Hi - I'm trying to run the spatial quick-start application and am getting the following error:

"sbt.librarymanagement.ResolveException: Error downloading edu.stanford.cs.dawn:spatial_2.13:1.1-SNAPSHOT"

I've changed nothing but the scala version in build.sbt and believe have all necessary dependencies installed.

It seems like there is a version discrepancy? The complete terminal output is attached.

macos

sbt version: 1.3.10

scala: 2.13.2

openjdk: 13.0.2

Thanks!

Hi.  The quick fix to this is to use scala 2.12 instead.  We just haven't published jars for 2.13 yet.  If you need scala 2.13, you can probably get it going yourself instead of waiting for the new jar to be published if you work with spatial from source (https://github.com/stanford-ppl/spatial instead of https://github.com/stanford-ppl/spatial-quickstart).  It should just be a matter of changing the build.sbt there unless if there are some incompatibilities.

Ok that did work but I am still having issues with dependencies. I believe this is a basic library dependency problem but I can't seem to get it together. The error I'm now getting when make install-ing both spatial-quickststart and spatial is:

"java.io.IOError: java.lang.RuntimeException: /packages cannot be represented as URI"

I tried installing jdk1.8 and setting the JAVA_HOME path variable but that resulted in no change. Any help with this headache is much appreciated!

I haven't seen this particular error before but it sounds like it is related to sbt/scala/jdk versions.  From what I saw, I'm guessing it could be fixed by using an older sbt or scala 2.12.10.  These versions of sbt and jdk should work for now while I try to work out the kinks with newer versions of everything.

Sorry about all the java/scala pain!

No worries! It's all on my end.

My java versions are slightly different so I'll fix those and everything should work fine.

Thanks for the info

Got it working! Just needed to properly source jdk1.8. Thanks for the help and loving Spatial. So far my favorite structured framework for accelerated applications out of the variety I've tested.

Cool!  Feel free to ask about anything if you get stuck.  Most likely there is an example or tutorial I can point you towards that could be hard to find on your own, depending on how complex your work gets.
