java - AWS Lambda Package Native Executable with JAR -


i have app runs on jvm, provided fat jar. needs invoke native linux binary, example ffmpeg. directory structure zip file need contain in order package both jar , executable together? cannot find documentation, code examples using build tools have not worked with.

let's pretend name of lambda blah. hoping answer like:

deployable jar contains:   + blah/  # contains fat jar   + lib/  # contains ffmpeg

here bash script wrote not work. puts fat jar , native executable in dist/ directory before zipping them together.

fatjar=blah-assembly-0.0.4.jar mkdir -p dist/ rm -f dist/* rm -f $deployed_zip cp $fatjar dist/ cp /usr/local/bin/ffmpeg dist/ (cd dist && zip -r $fatjar ffmpeg && mv $fatjar ../$deployed_zip)

any structure of zip file long native binary included in package appears in path or invoked through full path. in both cases means must update java code in 1 of following ways:

  1. modify path environment variable or
  2. call binary full path.

as of writing path of directory package contents extracted on aws lambda system can read lambda_task_root environment variable.

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
