GraalJS错误:无法初始化类com.oracle.truffle.js.runtime.JSContext
提问于 2022-05-22 23:23:37
我试图在实例中使用GraalJS来呈现服务器端。但是，当试图使用GraalJS运行代码时，我遇到了问题。每当我运行它时，我都会被抛出一个异常。
org.graalvm.polyglot.PolyglotException: java.lang.NoClassDefFoundError: Could not initialize class com.oracle.truffle.js.runtime.JSContext

at org.graalvm.polyglot.Context.eval(Context.java:379) [xxxxxxxxxxxxx:2.1.0.SNAPSHOT]这是我的密码：
try {
Context engine = Context.create("js");
Source source = Source.newBuilder("js", script, "<shell>").buildLiteral();
Value value = engine.eval(source);
if (value != null) {
return value.toString();
}
} catch (Exception e) {
e.printStackTrace();
}我用这些JVM参数运行我的实例：
java -XX:+UnlockExperimentalVMOptions -XX:+EnableJVMCI -XX:+UseJVMCICompiler
--module-path=~/aem/graalvm/graal-sdk-21.3.0.jar:~/aem/graalvm/truffle-api-21.3.0.jar
--upgrade-module-path=~/aem/graalvm/compiler-21.3.0.jar:~/aem/graalvm/compiler-management-21.3.0.jar
-cp ~/aem/graalvm/launcher-common-21.3.0.jar:~/aem/graalvm/js-launcher-21.3.0.jar:~/aem/graalvm/js-21.3.0.jar:~/aem/graalvm/truffle-api-21.3.0.jar:~/aem/graalvm/graal-sdk-21.3.0.jar:~/aem/graalvm/js-scriptengine-21.3.0.jar:~/aem/graalvm/regex-21.3.0.jar:~/aem/graalvm/icu4j-70.1.jar
... 据我所知，所有必需的依赖项(包括该类所属的js库)都存在于我的类路径和项目的依赖项中。我可以很好地运行单元测试，只有在实际的AEM实例中运行时才会出现这个问题。

我发现了问题所在，结果发现我缺少了icu4j依赖项，并且没有在包的<Import-Package>标记中导入它。
