Using sbt to build command line application - scala

Anybody successfully followed
http://www.scala-sbt.org/0.13/docs/Command-Line-Applications.html
using latest sbt 0.13.7 ?
I get unresolved dependency "org.scala-sbt#command;0.12.0: not found" for 0.12.0.
Trying command version 0.13.7 gets compile errors in Main.scala file around initialGlobalLogging:
[error] Unspecified value parameter console.
[error] GlobalLogging.initial(MainLogging.globalDefault _, File.crea
teTempFile("hello", "log") )
[error] GlobalLogging.initial(MainLogging.globalDefault _, File.crea
teTempFile("hello", "log") )
Thank you


0.13.7 seems to have updated the type and number of parameters for GlobalLogging.initial().
(http://www.scala-sbt.org/0.13.7/api/#sbt.GlobalLogging$)
Try changing the last two lines in Main.scala:
from
/** Configures logging to log to a temporary backing file as well as to the console.
* An application would need to do more here to customize the logging level and
* provide access to the backing file (like sbt's last command and logLevel setting).*/
def initialGlobalLogging: GlobalLogging =
GlobalLogging.initial(MainLogging.globalDefault _, File.createTempFile("hello", "log"))
to
val consoleOut = ConsoleOut.systemOut
def initialGlobalLogging: GlobalLogging =
GlobalLogging.initial(MainLogging.globalDefault(consoleOut).apply, java.io.File.createTempFile("hello", "log"), consoleOut )


Yes, I got same error. However, the error was resolved by renaming the file as "project/build.properties" and specifying the file via -Dsbt.repository.config:
~/Documents/spark/hello $ sbt -Dsbt.repository.config=./project/build.properties

After switching to Sleuth 3.0.2 TracerContext is always null

The field that is being injected.
#Autowired
protected Tracer tracer;
The line that is throwing NPE:
tracer.currentSpan().context().traceId();
The currentSpan() method, where ThreadContext is null.
#Nullable
public Span currentSpan() {
TraceContext context = this.currentTraceContext.get();
return context == null ? null : new LazySpan(this, context);
}
Also this line is producing null: String traceId = MDC.get("X-B3-TraceId");
MDC.getCopyOfContextMap(); returns an empty map.
Here is the code of the method for the completeness of the picture:
#GetMapping(path = "/user", produces = APPLICATION_JSON_VALUE)
#RequiresPermissions(IAM_USER_GET_PERMISSION)
public Object getMyself() {
UserContext userContext = (UserContext) SecurityUtils.getSubject().getPrincipal();
String traceId = MDC.get("X-B3-TraceId");
System.out.println(traceId);
System.out.println(MDC.getCopyOfContextMap());
OperationContext operationContext = OperationContext.newInstance(userContext, tracer.currentSpan().context().traceId());
UserBO user = identityManager.getMyself(operationContext);
return ResponseEntity.status(HttpStatus.OK).body(new UserEnvelopeDTO(iamDTOMapper.mapScoped(user, user.getActiveOrganizationId())));
}
As you can see this is an HTTP thread, that doesn't get MDC properly populated.
Also, I have this bean configured:
#Bean
public CurrentTraceContext.ScopeDecorator legacyMDCKeys() {
return MDCScopeDecorator.newBuilder()
.clear()
.add(CorrelationScopeConfig.SingleCorrelationField.newBuilder(BaggageFields.TRACE_ID)
.name("X-B3-TraceId").build())
.add(CorrelationScopeConfig.SingleCorrelationField.newBuilder(BaggageFields.PARENT_ID)
.name("X-B3-ParentSpanId").build())
.add(CorrelationScopeConfig.SingleCorrelationField.newBuilder(BaggageFields.SPAN_ID)
.name("X-B3-SpanId").build())
.add(CorrelationScopeConfig.SingleCorrelationField.newBuilder(BaggageFields.SAMPLED)
.name("X-Span-Export").build())
.build();
}

kie-maven-plugin fails to generate model with a mix of Java and DRL facts

I'm trying to generate a fully compiled kmodule with kie-maven-plugin. It works when all facts are defined in DRL, but fails when some facts are defined as Java POJOs.
In the same project:
Java fact (src\main\java\org\example\FactA.java):

this.propA = propA;
}
public String getPropA() {
return propA;
}
public void setPropA(String propA) {
this.propA = propA;
}
}
DRL Fact (src\main\resources\org\example\decB.drl):
package org.example
import org.example.FactA
declare FactB
factA: FactA
propB : String
end

It's probably a bug in the generation of declared types with the executable model.
Can you kindly post your reproducer here?
https://issues.jboss.org/projects/DROOLS/issues
In the meanwhile, as a workaround, can you try use the fully qualified name while using the class in the declared type?
package org.example
declare FactB
factA: org.example.FactA
propB : String
end
I've tried this against current master and it works.
Thanks for your help
It was a bug fixed here

Thanks for reporting

Is there a scalaTest method or attribute that can be used to run ONLY once just after all tests in all suites

I have a group of test suites that will grow too, and I need to run a testcleanup task that should run only once just after all the tests have finished execution and before the test process exits. This is similar to .NET AssebmlyCleanup, but I couldn't find something equivalent in the Scala/Scalatest world without having to do custom code, is there?
Thanks

I've been thinking how to approach this and one way to do this is to override a bit test and testOnly in our build.sbt.
So suppose we have under src/test/scala following two suites:
class Suite1 extends FlatSpec{
"Test1 in Suite1" should "succeed" in{
succeed
}
}
and
class Suite2 extends FlatSpec{
"Test1 in Suite2" should "succeed" in{
succeed
}
}
Now let's add under the /project/ folder a CleanUp.scala object where our cleanup will live:
object CleanUp{
def cleanUp:Unit = println("Cleaning up after all suites are completed.")
}
That's a minimal example, actually you may have there whatever complex cleanup you need.
Now in our build.sbt let's add following:
(test in Test) := {
val testsResult = (test in Test).value
CleanUp.cleanUp
testsResult
}
(testOnly in Test) := {
(testOnly in Test).evaluated
CleanUp.cleanUp
}
This overrides the default behavior of the test and testOnly tasks so the cleanup will be applied after all suites (or all specified by the user suites) are executed.
For example, here is my sbt console check of the new testOnly:
[IJ]sbt:AfterAllTests> testOnly Suite1
[info] Suite1:
[info] Test1 in Suite1
[info] - should succeed
[info] Run completed in 150 milliseconds.
[info] Total number of tests run: 1
[info] Suites: completed 1, aborted 0
[info] Tests: succeeded 1, failed 0, canceled 0, ignored 0, pending 0
[info] All tests passed.
Cleaning up after all suites are completed.
[success] Total time: 0 s, completed Dec 2, 2017 12:19:48 AM
[IJ]sbt:AfterAllTests>
And here is check of new test:
[IJ]sbt:AfterAllTests> test
[info] Suite2:
[info] Test1 in Suite2
[info] - should succeed
[info] Suite1:
[info] Test1 in Suite1
[info] - should succeed
[info] Run completed in 164 milliseconds.
[info] Total number of tests run: 2
[info] Suites: completed 2, aborted 0
[info] Tests: succeeded 2, failed 0, canceled 0, ignored 0, pending 0
[info] All tests passed.
Cleaning up after all suites are completed.
[success] Total time: 2 s, completed Dec 2, 2017 12:28:25 AM
[IJ]sbt:AfterAllTests>
As you can see cleanup gets invoked.
Hope this helps.

Gwt Overlay Compilation error whenever method gets used

I am trying to test getting rid of gwt-rpc entrypoints and instead use JAX-RS / JSON based entrypoints.
To do this, I am simply using the native GWT RequestBuilder apis.
As per the documentation here referenced next.
http://www.gwtproject.org/doc/latest/tutorial/JSON.html
The problem I am facing is that the compiler seems unhappy about letting me make use of any overlay API, namely any method that has no java code to be compiled and that is flagged as native.
I am of course using the latest, and greatest, gwt 2.8 compiler.
If I write my overlay as follows.
public class UserLoginGwtRpcMessageOverlay extends JavaScriptObject {
/**
* Mandatory PROTECTED no arguments constructor.
*/
protected UserLoginGwtRpcMessageOverlay() {
super();
}
public final native String getUserName(); /*
* { return userName; }
*/
public final native String getHashedPassword(); /*
* { return hashedPassword;
* }
*/
public final String toStringOverlay() {
return getUserName() + "-" + getHashedPassword();
}
The class will not compile.
And it will not compile because my artifical toString is making use of the overlay APIs, e.g. ( getUserName()).
If I were to take those calls out of the class, it the compiler would not break handling the class.
Going further, If I try to make a rest call as follows:
private void invokeRestService() {
try {
// (a) prepare the JSON request to the server
RequestBuilder builder = new RequestBuilder(RequestBuilder.POST, JSON_URL);
// (b) send an HTTP Json request
Request request = builder.sendRequest(null, new RequestCallback() {
// (i) callback handler when there is an error
public void onError(Request request, Throwable exception) {
LOGGER.log(Level.SEVERE, "Couldn't retrieve JSON", exception);
}
// (ii) callback result on success
public void onResponseReceived(Request request, Response response) {
if (200 == response.getStatusCode()) {
UserLoginGwtRpcMessageOverlay responseOverlay = JsonUtils
.<UserLoginGwtRpcMessageOverlay>safeEval(response.getText());
LOGGER.info("responseOverlay: " + responseOverlay.getUserName());
} else {
LOGGER.log(Level.SEVERE, "Couldn't retrieve JSON (" + response.getStatusText() + ")");
}
}
});
} catch (RequestException e) {
LOGGER.log(Level.SEVERE, "Couldn't execute request ", e);
}
}
Again, the compilation shall fail.
Once more this is the result of me trying to use the getUserName().
In particular, the followig line of code breaks the compiler.
LOGGER.info("responseOverlay: " + responseOverlay.getUserName());
Given that the compiler is running null pointer exceptions giving no other hint besides:
<no source info>: <source info not available>
I suspect I am dealing either with a compiler bug, or a feature that somehow got de-supported and whose APIs still linger. But at the same time, I would be surprised as I would assume overlays to be a core part of GWT, this should just work. So more likely I have some bug in the code I am not spotting.

Is anyone else experiencing problems in GWT 2.8 with overlays, or am I making some sort of mistake of which I am not aware.
Kind regards,
Any good pointer is appreciated.

public final native String getUserName(); /*
* { return userName; }
*/
This is not valid JSNI (with the same issue in getHashedPassword()). The correct way to write this would be
public final native String getUserName() /*-{
return userName;
}-*/;
You must start with /*-{ and end with }-*/;, and not have *s inbetween like Javadoc might.
However, as JS, that doesn't make any sense, so while it will compile, it isn't what you want. The body of the method should read
return this.userName;
since JS doesn't have an implicit this like Java does.
At a brief glance, the rest looks okay, but without legal JSNI, the compiler cannot accept it.

Why does sbt fail to resolve spongeapi dependency that gradle can find fine?

I'm getting the following error when attempting to build a project that has previously built fine.

However, using the same dependency on a java/gradle project works fine without error, and the dependency resolves fine.
build.gradle
group 'au.id.rleach'
version '0.1-SNAPSHOT'
apply plugin: 'java'
sourceCompatibility = 1.8
dependencies {
testCompile group: 'junit', name: 'junit', version: '4.11'
compile 'org.spongepowered:spongeapi:2.1-SNAPSHOT'
}
repositories {
mavenCentral()
maven {
name = 'sponge'
url = 'http://repo.spongepowered.org/maven'
}
}

I wasn't able to reproduce this issue using sbt 0.13.9.

The only change I made from your build file was commenting out the last line since you didn't specify to use sbt-assembly.
