How to actually install/run GraalJS?

[Pecacheu]

I'm trying to update project that previously worked just fine on GraalVM for JDK 17. On the older version, you install JS via gu install js and then ScriptEngine just works. Nice and simple. On the newer versions, not so much. gu is now removed and not supported, so how do I install JS into GraalVM? I'm using Maven, and I've tried adding all these dependencies to my pom.xml as described:

<properties>
	<java.version>23</java.version>
	<graalvm.version>24.1.0</graalvm.version>
	<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>

<dependency>
	<groupId>org.graalvm.polyglot</groupId>
	<artifactId>polyglot</artifactId>
	<version>${graalvm.version}</version>
</dependency>
<dependency>
	<groupId>org.graalvm.js</groupId>
	<artifactId>js-scriptengine</artifactId>
	<version>${graalvm.version}</version>
</dependency>
<!-- runtime -->
<dependency>
	<groupId>org.graalvm.polyglot</groupId>
	<artifactId>js-community</artifactId>
	<version>${graalvm.version}</version>
	<type>pom</type>
	<scope>runtime</scope>
</dependency>
<dependency>
	<groupId>org.graalvm.polyglot</groupId>
	<artifactId>profiler-community</artifactId>
	<version>${graalvm.version}</version>
	<type>pom</type>
	<scope>runtime</scope>
</dependency>
<dependency>
	<groupId>org.graalvm.polyglot</groupId>
	<artifactId>inspect-community</artifactId>
	<version>${graalvm.version}</version>
	<type>pom</type>
	<scope>runtime</scope>
</dependency>

I then set my JDK to GraalVM 23 (GraalJS 24.1.0 said to use GraalVM 23) in IntelliJ and build with clean package. On my Linux server, I install the same GraalVM version into /usr/lib/jvm/graalvm. Then I run my JAR using JAVA_HOME=/usr/lib/jvm/graalvm /usr/lib/jvm/graalvm/bin/java -jar <name>

Important part of the code:

ScriptEngineManager manager = new ScriptEngineManager();
engine =  manager.getEngineByName("graal.js");
if(engine == null) throw new Exception("Engine not found!");

Problem is, engine is always null. Again, running the same code on the previous version with gu install js, this all works.

@Pecacheu Can you try to make so the js-scriptengine dependency is the above the org.graalvm.polyglot?

I was having the same issue and after making this change I got it to work again. You can find the order I mention here.

Let me know if it helps.
