I have the following in my build.gradle:
compile "io.dropwizard.metrics:metrics-core:3.1.0"
compile "io.dropwizard.metrics:metrics-servlet:3.1.0"
compile "io.dropwizard.metrics:metrics-healthchecks:3.1.0"
On inspection of metrics-servlet, I see:
According to https://dropwizard.github.io/metrics/3.1.0/manual/servlets/,
"The metrics-servlets module provides a handful of useful servlets", including HealthCheckServlet, MetricsServlet, and ThreadDumpServlet.
Where are these Servlets if not in metrics-servlet!?
There are both a metrics-servlet and metrics-servlets module. Servlet contains abstract framework classes and servlets contains the concrete implementations.
This works:
compile "io.dropwizard.metrics:metrics-core:3.1.0"
compile "io.dropwizard.metrics:metrics-servlet:3.1.0"
compile "io.dropwizard.metrics:metrics-servlets:3.1.0"
compile "io.dropwizard.metrics:metrics-healthchecks:3.1.0"
And actually, only the following is needed:
compile "io.dropwizard.metrics:metrics-servlets:3.1.0"
compile "io.dropwizard.metrics:metrics-healthchecks:3.1.0"

I'm trying to adopt debugging in graaljs:
Context.newBuilder("js")
.option("inspect", port)
.option("inspect.Path", path)
.option("inspect.Remote", remoteConnect)
java.lang.IllegalArgumentException: Could not find option with name inspect.
My build.gradle dependencies look as follows:
def graalVersion = "1.0.0-rc15"
dependencies {
compile "org.graalvm.sdk:graal-sdk:${graalVersion}"
compile "org.graalvm.js:js:${graalVersion}"
compile "org.graalvm.js:js-scriptengine:${graalVersion}"
}
And I definitely remember that there used to be yet another dependency I should add to make it possible to debug in chrome - however I'm failing to remember - or find in any code source or documentation - what exactly I should add as a dependency
I think you should also include the chromeinspector.
In maven that would be:
<dependency>
<groupId>org.graalvm.tools</groupId>
<artifactId>chromeinspector</artifactId>
<version>1.0.0-rc15</version>
</dependency>
I'm currently attempting to start a project using JavaCV in Kotlin. I'm using IntelliJ Idea as my IDE. I'm using JavaCV 1.3.2 and OpenCV 3.20.
This is my setup for the module's dependancies for OpenCV:
and for JavaCV:
I have opencv before javacv in the dependancies.
To test that OpenCV is present and valid, I wrote the below to test. As I can loadLibrary and the version number shows correctly I can assume that OpenCV is actually working.
import org.opencv.core.Core
import org.opencv.core.Mat
import org.opencv.core.CvType
import org.opencv.core.Scalar
import org.bytedeco.javacv.OpenCVFrameGrabber
fun main(args : Array<String>) {
println("Test Built Successfully")
System.loadLibrary(Core.NATIVE_LIBRARY_NAME)
println("Running OpenCV Version ${Core.VERSION}")
val grabber = OpenCVFrameGrabber(1)
}
The line where we initialize the grabber rasies the following exception:
Exception in thread "main" java.lang.UnsatisfiedLinkError: no jniopencv_core in java.library.path
Caused by: java.lang.UnsatisfiedLinkError: no opencv_imgproc320 in java.library.path
Perhaps I am missing something here, but I have followed the instructions provided by the README.md in the Git repository for JavaCV. I haven't seen anybody else trying to use this library with Kotlin on StackOverflow, though have checked out some posts about the same exception being raised using java.
Handling this error is no different in Kotlin from Java; you need to specify the path to the native libraries for opencv. By default on Windows it will look for the native libraries in whatever is set in your PATH environment variable.
You can also explicitly specify which directory to look for the native libraries by specifying the system property java.library.path (as indicated by the error message).
For example, you can add a run configuration like this:
Where ${PATH_TO_DYNAMIC_LIB} would be where ever the native lib opencv_imgproc320.dll is - I think in your case it would be C:/Users/ms/IdeaProjects/CVTest/opencv/build/java/x64.
I was able to resolve this by leaving my VM options blank and adding all necessary OpenCV libraries as native library paths in my JavaCV library configuration.
on MacOS, you don't need to install a native library. On OpenCV3.41, as fetched from
<!-- https://mvnrepository.com/artifact/org.openpnp/opencv -->
<dependency>
<groupId>org.openpnp</groupId>
<artifactId>opencv</artifactId>
<version>3.4.2-1</version>
</dependency>
I looked in the library (jar tf ~/.m2/repository/org/openpnp/opencv/3.4.2-1/opencv-3.4.2.-1.jar) and found dlls and whatnot in it:
jar tf *1.jar | grep nu
...
nu/pattern/opencv/osx/
nu/pattern/opencv/osx/x86_64/
nu/pattern/opencv/osx/x86_64/README.md
nu/pattern/opencv/osx/x86_64/cmake.log
nu/pattern/opencv/osx/x86_64/libopencv_java342.dylib
...
This led me to this StackOverflow question on nu.pattern which show how to use the nu.pattern in code.
static {
nu.pattern.OpenCV.loadShared();
System.loadLibrary(org.opencv.core.Core.NATIVE_LIBRARY_NAME);
}
This prologue code enabled sample apps which used to fail as above to run.
I get repetitive method name/Signature compilation failure when i try to use i18nFields in my domain class to support multiple languages.
Grails Version : 2.3.7 ( I tried with 2.3.4 and got the same issue and upgraded)
Documentation from Grails followed for this was http://grails.org/plugin/i18n-fields
My Domain class looks like
package com.sampleapp.domain
import i18nfields.I18nFields;
#I18nFields
class Products {
def name
static constraints = {}
static i18nFields = ['name']
}
My Config.groovy has the below line included to specify the locale
// internationalization support - testing
i18nFields {
locales = ['en','es']
}
BuildConfig.groovy plugin definition
plugins {
// plugins for the build system only
build ":tomcat:7.0.47"
// plugins for the compile step
compile ":scaffolding:2.0.1"
compile ':cache:1.1.1'
// plugins needed at runtime but not for compilation
runtime ":hibernate:3.6.10.6" // or":hibernate4:4.1.11"//
runtime ":database-migration:1.3.8"
runtime ":jquery:1.10.2.2"
// compile ":jquery-ui:1.10.2.2"
runtime ":resources:1.2.1"
// Uncomment these (or add new ones) to enable additional resources capabilities
runtime ":zipped-resources:1.0.1"
runtime ":cached-resources:1.1"
//runtime ":yui-minify-resources:0.1.5"
compile ':platform-core:1.0.RC6'
compile ":cache-headers:1.1.5"
runtime ':spring-security-core:2.0-RC2'
// internationalization
compile ":i18n-fields:0.8.1"
}
The compilation error is
grails-workspace\Test\grails-app\domain\com\sampleapp\domain\Products.groovy: -1: Repetitive method name/signature for method 'void setName_es(java.lang.String)' in class 'com.sampleapp.domain.Products'.
# line -1, column -1.
The Error is repeated for the name property for both en and es locales twice.
There is no error if i remove the i18nFields annotation and the sample app worked fine before this. I verified GGTS repetitive method name/signature error in controllers post for similar error in controller. I have also verified to ensure that groovy version is correct and in my case it is 2.1
Can somebody please give me any pointers on where i should look to resolve this issue.
This problem shows up when you are trying to use Java > v7 with any version of Grails < 2.3.7. Either downgrade your jvm or upgrade your grails.
Thanks for trying (and for making me know via github ;) )
The issue was known but hadn't been tackled yet.
The previous answer (commenting out methods) is not exact, event though it follows the right track, because the problem comes from new changes in Grails that will cause a collision in getters and setters.
The solution I've found is to separately create the property and the getter/setter, and it seems to work.
I'm releasing a new version as soon as it can be fully tested in a project, but code is already available in https://github.com/jorgeuriarte/grails-i18n-fields-plugin/tree/redis_integration (version 0.9-redis-SNAPSHOT) in case you want to use it.
Probably it has something to do with the new Binding mechanism in grails 2.3. Maybe the getters and setters are set automatic now?
When I comment out these two lines in ClassI18nalizator.groovy the error disappears. It seems to work at least partly. I can use the fields in scaffolding. It's not a real solution but maybe a hint for someone who understands grails better than me.
private def getSetterMethod(field) {
// setter should return void. that's why the return statement.
//return new AstBuilder().buildFromString("i18nfields.I18nFieldsHelper.setValue(this, '${field}', value); return;").pop();
}
private def getGetterMethod(field) {
//new AstBuilder().buildFromString("i18nfields.I18nFieldsHelper.getValueOrDefault(this, '${field[0..-7]}', '${field[-5..-1]}')").pop();
}
After that I run into a second issue:
No signature of method: groovy.util.ConfigObject.contain() is
applicable for argument types: (java.lang.String) values: [en_US]
I solved it by adding redisLocale to Config.groovy
i18nFields {
locales = ['de_DE', 'en_US']
defaultLocale = "en_US"
redisLocales = ['de_DE', 'en_US']
}
Using grails 2.3.2, Java 1.6.0_65, trying to compile the following placed in the services directory. Even if it is not a service, and just put in the src/groovy directory, it still causes the same compile error.
I installed groovy 2.1.9 (and tried 2.2.0) which appears to be the version used by grails 2.3.2 and ran groovyc -cp quava-13.0.1.jar TestCache.groovy and it worked fine. So it appears to be something related to grails.
package somewhere
import com.google.common.cache.Cache
import groovy.transform.CompileStatic
#CompileStatic
class TestCacheService {
private final Cache<URL, String> cache
TestCacheService() {
cache = null
}
}
I receive the following error:

Is this a known bug?
Any workaround?
Google's Cache class uses the Nullable annotation. I had multiple nullable annotation implementations on my classpath. I think removing 'edu.washington.cs.types.checker:checker-framework:1.6.4' from the classpath solved this problem.
I'm using Grails and want to use groovyws to call an web-service.
But my groovyws.jar (0.5.2) have MANY dependences that I can't solve.
Is there any jar with all dependences included?
Note: I tried put in BuildConfig.groovy, this
dependencies {
'org.codehaus.groovy.modules:groovyws:0.5.2'
}
but I'm getting error:
Error executing script Compile: loader constraint violation: when
resolving overridden method
"org.apache.xerces.jaxp.SAXParserImpl.getParser()Lorg/xml/sax/Parser;"
the class loader (instance of
org/codehaus/groovy/grails/cli/support/GrailsRootLoader) of the
current class, org/apache/xerces/jaxp/SAXParserImpl, and its
superclass loader (instance of ), have different Class
objects for the type org/xml/sax/Parser used in the signature
You can manually exclude xerces by:
dependencies {
runtime('org.codehaus.groovy.modules:groovyws:0.5.2') {
exclude: 'xerces'
}
}
GroovyWS pulls inn CXF, which again pulls in a lot of dependencies, some of them conflicting with classes already present in Java 6. You need to exclude all these dependencies if using Java 6, to avoid errors like the one you mention.
Here's my exclude list:
compile("org.codehaus.groovy.modules:groovyws:0.5.2") {
excludes 'geronimo-servlet_2.5_spec', 'servlet-api', 'jaxb-xjc', 'jaxb-impl', 'xml-apis', 'saaj-impl', 'junit', 'slf4j-jdk14', 'xmlParserAPIs', 'jaxb-api', 'saaj-api', 'xmlbeans', 'jaxen', 'geronimo-stax-api_1.0_spec', 'geronimo-activation_1.0.2_spec', 'abdera-client', 'geronimo-activation_1.1_spec'
}
Note that on Ubuntu you need jaxb-xjc and jaxb-impl after all, don't know why.
I found:
http://docs.codehaus.org/dosearchsite.action?queryString=groovyws+standalone
Tks a lot!
(search for "groovyws standalone")
Note: I saw this tip here.
