Trying to run my eclipse plugin from within eclipse, I get error messages to the console, which make the nested eclipse fail to run the plugin:
org.osgi.framework.BundleException: Error starting module.
at org.eclipse.osgi.container.Module.doStart(Module.java:590)
...
Caused by: java.lang.Error: Unresolved compilation problems:
The import org.eclipse cannot be resolved
The import org.eclipse cannot be resolved
The import org.eclipse cannot be resolved
The import org.eclipse cannot be resolved
The import org.osgi cannot be resolved
AbstractUIPlugin cannot be resolved to a type
IStartup cannot be resolved to a type
The method earlyStartup() of type Plugin must override or implement a supertype method
BundleContext cannot be resolved to a type
BundleContext cannot be resolved to a type
Suggesting that my plugin has compilation errors to it, but:
The plugin has not compilation errors
It seems a bit surprising that running a plugin would cause a compilation.
There was indeed no compilation error: the problem lies elsewhere. The main
Plugin class was to be a singleton, which was implemented like so:
public class Plugin extends AbstractUIPlugin implements IStartup {
public static Plugin plugin;
/ ** an empty c'tor. creates an instance of the plugin. */
public Plugin() {
plugin = this;
}
....
}
Now, other classes were referring to this public field, which not initialized; for some reason, eclipse thought this was a compilation
error. It was not. using a getter for that field solved the problem.

I am trying out KTOR for building backend server application. When I try to include implementation("io.ktor:ktor-auth:1.6.8") dependency, it gives me an error
Supertypes of the following classes cannot be resolved. Please make sure you have the required dependencies in the classpath:
class io.ktor.auth.Authentication.Feature, unresolved supertypes: io.ktor.application.ApplicationFeature
Adding -Xextended-compiler-checks argument might provide additional information.
Type mismatch: inferred type is Authentication.Feature but Plugin<TypeVariable(P), TypeVariable(B), TypeVariable(F)> was expected
Here is the error
fun Application.authentication() {
install(Authentication) { // here is the error
jwt {
}
}
}
I looked at the Authentication.kt file and it does not have any plugin in it.
how to correct this?
I took the version from mvnrepository https://mvnrepository.com/artifact/io.ktor/ktor-auth/1.6.8
EDIT. I was able to resolve it by adding different dependencies
implementation("io.ktor:ktor-server-auth-jvm:$ktor_version")
implementation("io.ktor:ktor-server-auth-jwt-jvm:$ktor_version")
a project i'm working with has a dependency on kotlin.jvm.internal.Intrinsics. so i added kotlin-gradle-plugin-1.5.0.jar. now i'm getting an error that it can't find gson.streams. any idea what this is all about?
Error occurred during initialization of boot layer
java.lang.module.FindException: Error reading module: E:\jars\kotlin-gradle-plugin-1.5.0.jar
Caused by: java.lang.module.InvalidModuleDescriptorException: Package com.google.gson.stream not found in module
i already have gson-2.8,6.jar in my classpath.
The Jar kotlin-gradle-plugin version 1.5.0 seems to have runtime dependency with com.google.code.gson ยป gson
you can see that in the Runtime Dependencies section from here
In order to rectify this, you have to add it as a plugin
like below
plugins {
id 'org.jetbrains.kotlin.<...>' version '1.5.0'
}
This is the recommended way from here
Running instrumentation tests with RESTMock we are getting this error

This is the line in question in OkHttp
IIUC, Kotlin can treat a varargs as a Kotlin Array and then call extensions functions like copyInto
We're on OkHttp 4.0.1, Kotlin 1.3.40, R8 1.5.41
Our test apk correctly contains copyInto method so I don't think it's a proguard/R8 issue:
I'm at a loss as to what to test next. I asked on OkHttp's github issuse page and they suggested I post here link
Update: still happening on OkHttp 4.1.0. Also I realized that it can't be an R8 issue since R8 doesn't remove code from test apk.
I had a same issue , then added the mentioning lib to my project. It solved my problem:
maven :
<!-- https://mvnrepository.com/artifact/org.jetbrains.kotlin/kotlin-stdlib -->
<dependency>
<groupId>org.jetbrains.kotlin</groupId>
<artifactId>kotlin-stdlib</artifactId>
<version>1.3.70</version>
</dependency>
or
'org.jetbrains.kotlin:kotlin-stdlib:1.3.70'
I got the same issue when I was using okhttp3.mockwebserver.MockWebServer with https enabled with a server certificate from okhttp-tls.
In my case, the problem was that by just importing the com.squareup.okhttp3:okhttp-tls:4.2.0 dependency, org.jetbrains.kotlin:kotlin-stdlib was being resolved to version 1.2.71.
Given the copyInto method was introduced starting kotlin 1.3 it was failing with the same error you have.
I fixed it by adding explicitly the kotlin version in my gradle.build file:
testRuntime 'org.jetbrains.kotlin:kotlin-stdlib:1.3.50'
I got the same issue, but I'm developing a multi-module java project. It was useful that add a dependency for kotlin-stdlib in pom.xml that belongs to this module while unit testing...
When I boot this whole project, this issue came out agnain. Finally, I find this dependency need to be in the whole project's pom.xml, I mean the pom.xml in the project's root dir.
New to OkHttp, however I was able to track the following errors:
val url = "https://api.letsbuildthatapp.com/youtube/home_feed"
try {
val request = Request.Builder().url(url).build()
} catch(err: Error){
println("Request Error: $err")
}
This generates: "Request Error: java.lang.BootstrapMethodError: Exception from call site #5 bootstrap method"
try {
OkHttpClient()
} catch(err: Error){
println("Client Error: $err")
}
This returns an error "Client Error: java.lang.NoClassDefFoundError: okhttp3.internal.Util"
Any help with these will be greatly appreciated. TIA
It looks like you have an issue with the dependency and/or JVM. The java.lang.BootstrapMethodError may mean there is something work with the Java Runtime Environment. Please consider upgrading Java to the stable version (e.g. 11 or 1.8)
The NoClassDefFound error means you miss some classes from the OkHttp library in your project. There are likely to be several transitive dependencies from the .jar that you have in your project. Probably Gradle or Maven project will help to have all dependencies resolved correctly.
When using Log4j2 in Intellij for a groovy/gradle project, log shows up red as if the injection is not working. Gradle runs and builds but every file in IntelliJ shows errors which is annoying.
dependencies
compile 'org.codehaus.groovy:groovy-all:2.4.4'
compile 'org.apache.logging.log4j:log4j-api:2.5'
compile 'org.apache.logging.log4j:log4j-core:2.5'
Source
import groovy.util.logging.Log4j2
#Log4j2
class TestLog4j2 {
public static void log(String message) {
log.error(message)
log from log.error is displayed in red and displays error, cannot resolve symbol 'log'
The log4j2.xml file is in the classpath and works.
#Log4j and even #Slf4j both work
Using IntelliJ 15.03 Build IU-143.1821
Project is using Groovy 2.4.4 and Gradle 2.3
Thoughts anyone?
I was getting this error when using groovy's #Log4j2 annotation.
The solution was to exclude the following module in gradle:
configurations.all {
exclude module: 'log4j-to-slf4j'
}
