IllegalStateException: No language and polyglot implementation was found on the classpath. Make sure the truffle-api.jar is on the classpath

Question

IllegalStateException: No language and polyglot implementation was found on the
classpath. Make sure the truffle-api.jar is on the classpath.

I wanted to use GraalVM in my Java project.

I added this dependency to my pom.xml

<dependency>
  <groupId>org.graalvm.js</groupId>
  <artifactId>js-scriptengine</artifactId>
  <version>1.0.0-rc10</version>
</dependency>

but apparently that's not enough.

What else do I have to do to fix this error?

Why did you add that specific dependency only? What did you read to think that was enough? --- Anyway, do what it says, find the dependency for truffle-api.jar and add that too. — Andreas, Jan 27 '19 at 02:38
There's a section called "Running Graal.js on a stock JDK** " here: https://stackoverflow.com/a/52200711/1087978 — Oleg Šelajev, Jan 27 '19 at 15:20

Had to add all these dependencies:

<dependency>
  <groupId>org.graalvm.js</groupId>
  <artifactId>js</artifactId>
  <version>1.0.0-rc10</version>
</dependency>
<dependency>
  <groupId>org.graalvm.js</groupId>
  <artifactId>js-scriptengine</artifactId>
  <version>1.0.0-rc10</version>
</dependency>
<dependency>
  <groupId>org.graalvm.truffle</groupId>
  <artifactId>truffle-api</artifactId>
  <version>1.0.0-rc10</version>
</dependency>
