kotlin getparameters function not working - kotlin

Question

I get constantly:
java.lang.IllegalStateException: Resource not found in classpath: kotlin/coroutines/coroutines.kotlin_builtins
while I try to get parameters of any object as pointet in example below:
::flagDbInfo.parameters
I've added following dependencies to my maven:
<dependency>
<groupId>org.jetbrains.kotlinx</groupId>
<artifactId>kotlinx-coroutines-core</artifactId>
<version>0.30.2</version>
</dependency>
<dependency>
<groupId>org.jetbrains.kotlin</groupId>
<artifactId>kotlin-reflect</artifactId>
<version>1.3.0</version>
</dependency>

Answer 1

Since you are using version 1.3.0 I would recommend the following dependency
<dependency>
<groupId>org.jetbrains.kotlin</groupId>
<artifactId>kotlin-reflect</artifactId>
<version>1.3.0</version>
</dependency>
<dependency>
<groupId>org.jetbrains.kotlin</groupId>
<artifactId>kotlin-stdlib</artifactId>
<version>1.3.0</version>
</dependency>

Got the same error, working on a Spring Boot app, with IntelliJ 2019.1, kotlin 1.3.30.
The following configuration (in pom.xml) fixed it:
<dependencies>
... (your other dependencies)
<dependency>
<groupId>org.jetbrains.kotlin</groupId>
<artifactId>kotlin-stdlib</artifactId>
<version>1.3.30</version>
</dependency>
<dependency>
<groupId>org.jetbrains.kotlin</groupId>
<artifactId>kotlin-reflect</artifactId>
<version>1.3.30</version>
</dependency>
</dependencies>
...
<plugins>
...
<plugin>
<artifactId>kotlin-maven-plugin</artifactId>
<groupId>org.jetbrains.kotlin</groupId>
<version>1.3.30</version>
<configuration>
<args>
<arg>-Xjsr305=strict</arg>
</args>
<jvmTarget>1.8</jvmTarget>
</configuration>
<executions>
<execution>
<id>compile</id>
<phase>compile</phase>
<goals> <goal>compile</goal> </goals>
<configuration>
<sourceDirs>
<source>src/main/java</source>
<source>src/main/kotlin</source>
</sourceDirs>
</configuration>
</execution>
<execution>
<id>test-compile</id>
<phase>test-compile</phase>
<goals> <goal>test-compile</goal> </goals>
</execution>
</executions>
</plugin>
...
</plugins>
Also, I originally had the kotlin-stdlib-jdk8 artifact as a dependency as well, but if the kotlin-stdlib artifact is included, the jdk8 one is not needed. See https://kotlinlang.org/docs/reference/whatsnew12.html#kotlin-standard-library-artifacts-and-split-packages for more details.
