I have an existing kotlin project. Now I'm trying to add the SolanaKT library to it.
I have added the JitPack repository maven { url 'https://jitpack.io' } and dependency implementation 'com.github.metaplex-foundation:SolanaKT:2.0.1'.
Then I did a gradle sync.
I try using:
val endPoint = RPCEndpoint.devnetSolana
val network = HttpNetworkingRouter(endPoint)
val solana = Solana(network)
But i get error Unresolved reference: RPCEndpoint.
What am I doing wrong? Is there anything else I should do (maybe copy some files to the project) ?

I created a gradle build config just to download some dependencies. The documentation has been sparse, so I've piece together this working snippet based on random snippets and guesses.
configurations {
create("downloadDeps")
}
dependencies {
// JSON
configurations["downloadDeps"]("com.fasterxml.jackson.core:jackson-databind:2.13.3")
configurations["downloadDeps"]("com.fasterxml.jackson.module:jackson-module-kotlin:2.13.3")
}
repositories {
// internal repository
maven {
url = uri("...")
credentials {
username = System.getenv("ARTIFACTORY_USER") ?: System.getProperty("ARTIFACTORY_USER") as String
password = System.getenv("ARTIFACTORY_TOKEN") ?: System.getProperty("ARTIFACTORY_TOKEN") as String
}
}
}
tasks.register<Copy> ("downloadDeps") {
from(configurations["downloadDeps"])
into("lib/")
}
If I reference the "downloadDeps" dependency like configuration.downloadDeps or downloadDeps("com.fasterxml.jackson.core:jackson-databind:2.13.3"). I get an error about an unresolved reference to "downloadDeps".
Why does implementation("...") or configuration.implementation.get() work?
The documentation #Slaw provided helped me understand why I can do something like this:
implementation("group:artifact:1.0.0")
but not
myCustomConfig("group:artifact:1.0.0")
implementation being declared that way is supported because it comes from a plugin (the Kotlin/Java plugins)
The simplest way to associate a dependency with myCustomConfig would be to do this (see these docs):
"myCustomConfig"("group:artifact:1.0.0")

Then I found a work around which add -bootclasspath path_to_sdk_android_jar_file in the other command-line argument text box in the JavaDoc dialog.
However, newer Java deprecated -bootclasspath. It throws another error as follows:
error: option --boot-class-path not allowed with target 11
So I used -sourcepath instead. That brought the old error (NullPointerException).
I am pretty much lost at this point.
By the way, if I choose a class with only Java elements (no-android) and create JavaDoc to that specific file only, it creates JavaDoc nicely. But this is not a good workaround for a project with a lot of classes.
I've faced the same issue as yours with several imports errors..
The following solution worked for me ( I got it from mike192's answer, see the link here )
task javadoc(type: Javadoc) {
doFirst {
configurations.implementation
.filter { it.name.endsWith('.aar') }
.each { aar ->
copy {
from zipTree(aar)
include "**/classes.jar"
into "$buildDir/tmp/aarsToJars/${aar.name.replace('.aar', '')}/"
}
}
}
configurations.implementation.setCanBeResolved(true)
source = android.sourceSets.main.java.srcDirs
classpath += project.files(android.getBootClasspath().join(File.pathSeparator))
classpath += configurations.implementation
classpath += fileTree(dir: "$buildDir/tmp/aarsToJars/")
destinationDir = file("${project.buildDir}/outputs/javadoc/")
failOnError false
exclude '**/BuildConfig.java'
exclude '**/R.java'
}
All you need to do is to add the code to your build.gradle file right before your dependencies {}
Then, double click on your Ctrl button and execute the following command :
gradle javadoc
The result of the javadoc can be then found in your project's directory \app\build\outputs\javadoc
I hope this works for you
I need to retrieve some user specific parameters from Gradle build file in an Intellij project (build.gradle.kts)
Here a "build.gradle.kts" file content example I need to parse:
cutomParameters {
param1.set("any value")
sub_parameters1 {
sub_parameter1_1.set("foo")
}
subParameters2 {
subParameter21("foo")
subParameter22 {
subParameter221.set("foo")
}
}
}
I tried some code like this:
val connection: ProjectConnection =
GradleConnector.newConnector().forProjectDirectory(File(projectPath)).connect()
val model = connection.model(GradleBuild::class.java)
I can get the gradle build file using model.get().buildFile but how to retrieve the custom parameters described in the previous example?
I want to write a telegram bot and use this library from Github for that. In this telegram bot I need to make some requests to another service, so I want to use the ktor client library for that. However when I try to instantiate the ktor httpClient I get the following exception:
Exception in thread "main" java.lang.NoSuchMethodError: 'void io.ktor.util.collections.ConcurrentMap.<init>(io.ktor.util.Lock, int, int, kotlin.jvm.internal.DefaultConstructorMarker)'
at io.ktor.client.engine.cio.CIOEngine.<init>(CIOEngine.kt:32)
at io.ktor.client.engine.cio.CIO.create(CIOCommon.kt:23)

at io.ktor.client.HttpClientJvmKt.HttpClient$default(HttpClientJvm.kt)
at problem.ktor.MainKt.main(Main.kt:9)
at problem.ktor.MainKt.main(Main.kt)
I made a new project and narrowed the problem down to the telegram bot library, which apparently conflicts with the kotr library. I assume some version conflict of the kotr library, because that's where the exception happens. How can I solve the conflict?
Here is a minimal reproducible example. Use the following build.gradle.kts file:
import org.jetbrains.kotlin.gradle.tasks.KotlinCompile
plugins {
application
kotlin("jvm") version "1.4.30"
}
repositories {
mavenCentral()
maven(url = "https://jitpack.io")
}
dependencies {
implementation("io.ktor:ktor-client-core:1.5.2")
implementation("io.ktor:ktor-client-cio:1.5.2")
implementation("com.github.kotlin-telegram-bot:kotlin-telegram-bot:6.0.4")
}
And run the following minimal main function:
import io.ktor.client.*
fun main() {
HttpClient()
}
Maybe it's important, I use Java 15.0.2.
The problematic dependency is com.github.kotlin-telegram-bot.kotlin-telegram-bot:webhook:6.0.4. As a workaround you can exclude it since it's just a sample:
implementation("com.github.kotlin-telegram-bot:kotlin-telegram-bot:6.0.4") {
exclude(module = "webhook")
}
I a new to Kotlin and Ktor in particular, so I have tried to do simple post request. As you can see below, there is nothing special.
routing {
post("/articles/add"){
val post = call.receive<ArticleRequest>()
println(post)
}
Error shown in logs is below and I don't understand why I should use here coroutines.
ERROR Application - Unhandled: POST - /articles/add
java.lang.IllegalStateException: Using blocking primitives on this dispatcher is not allowed. Consider using async channel instead or use blocking primitives in withContext(Dispatchers.IO) instead.
I am using 1.4.2 version. I would appreciate any help.
If you are using Jackson this is a bug and there is a suggested workaround:
routing {
post("/articles/add") {
with(Dispatchers.IO) {
val post = call.receive<ArticleRequest>()
println(post)
}
}
}
Or you can rollback to 1.4.1 until the bug is solved.
I've experienced the same issue after upgrading to ktor 1.4.2 and Kotlin 1.4.20, and I used both Moshi and Gson on this specific project but I don't believe they are causing this issue.
If you have a 'gradle.properties' file, add these ( or whatever version you wish to use ) :
ktor_version=1.3.2
kotlin_version=1.3.70.
Otherwise, in your 'build.gradle' file, create variables for different version :
buildscript {
ext.kotlin_version = '1.3.70'
ext.ktor_version = '1.3.2'
repositories {
jcenter()
}
dependencies {
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
}
}
Then sync your gradle, run project.. all should be good.
However if you still experience some gradle-related issue, try this :
go to gradle (folder) -> wrapper -> open gradle_wrapper.properties and make sure the url has version 6.x.x or 5.x.x.
Mine looks like this currently:
distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-6.6.1-all.zip
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
