mysql - Character encodings of strings in gradle -


so in gradle build, why java string

"foo" acceptable mysql database utf-8 encoding, gstring "${somevalue}" not be?

what's happening this:

sql.withtransaction { def batchresult = sql.withbatch(   20,   'insert table(job_id, log_name, scenario_name, classification, value) values (?,?,?,?,?)'){  stmt ->     rows.each  {  r ->       def jobid = "${system.getenv('job_name')}:${system.getenv('build_number')}"       def classifier = "{'observer_id':${r['observer_id']}, 'sensor_name':${r['sensor_name']}}"        stmt.addbatch(                jobid,                "foo",                project.scenariofilename,                classifier,                r['count(1)'])      }   }

this fails because utf-8 encoded database rejects value of jobid (and project.scenariofilename, , classifier), spewing escaped characters \xac unacceptable.

but what's funny is, if this

      stmt.addbatch(         new string(jobidstr.getbytes("utf-16"),"utf-8"),         "foo",         new string(project.scenariofilename.getbytes("utf-16"),"utf-8"),         new string(classifier.getbytes("utf-16"),"utf-8"),         r['count(1)']       )

it works.

so why "foo" seen utf-8, "${system.getenv('job_name')}" not?

incidentally, setting systemprop.file.encoding=utf-8 in gradle.properties doesn't change anything.

add .tostring() @ end of gstrings ("${..}:${..}".tostring()) when using in groovy sql.

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. :)
