我尝试使用 nashorn-core:15.1.1.jar 和 Java 17（预发布 - build 27）运行我们产品的 ANT 版本，我得到：

我们在一些 ANT 构建文件中使用嵌入式 javascript 代码，并将 Nashorn 功能内置到 Java 8+ 中。在 Java 15 中，Nashorn 功能已被删除，因此我们使用独立的nashorn.jar文件对此进行了测试。我们刚刚添加：

<classpath> <pathelement location="<path>/nashorn.jar"/> </classpath>

一切进展顺利。对于 Java 16，这在构建 16+27 中运行良好。

当我运行一个简单的测试 ANT 脚本时，从 java 16+29（及更高版本）开始：

<project name="Test" default="build" basedir=".">
    <target name="build">
      <echo message="Begin"/>
      <script language="javascript">
        <classpath> <pathelement location="C:/nashorn/nashorn-0.1.0.2013070801.jar"/> </classpath>
        print('Hello from embedded Javascript');
      </script>
      <echo message="End"/>
    </target>
</project>

我收到以下错误：

build.xml:5: java.lang.IllegalAccessError: class jdk.nashorn.internal.codegen.types.Type (in unnamed module @0xeafc191) cannot access class jdk.internal.org.objectweb.asm.Type (in module java.base) because module java.base does not export jdk.internal.org.objectweb.asm to unnamed module @0xeafc191 …
