问题描述

我使用的是 Java11，我正在尝试使用 Java 客户端在 janusgraph 上执行一些 gremlin 脚本。

        String sessionId = UUID.randomUUID().toString();
        Map config = new HashMap();
        config.put("ioRegistries",Arrays.asList("org.janusgraph.graphdb.tinkerpop.JanusGraphIoRegistry"));
        MessageSerializer serializer = new GraphSONMessageSerializerV3d0();
        serializer.configure(config,null);     
        final Cluster cluster = Cluster.build().addContactPoint("xxx").port(yyyy).serializer(serializer)        .maxInProcessperConnection(32).maxSimultaneousUsagePerConnection(32).maxContentLength(1000000)              .maxWaitForConnection(10).minConnectionPoolSize(1).maxConnectionPoolSize(1).create();
        Client client = cluster.connect(sessionId);

But getting error : 
Exception in thread "main" java.lang.IllegalStateException: java.lang.classNotFoundException: org.janusgraph.graphdb.tinkerpop.JanusGraphIoRegistry
    at org.apache.tinkerpop.gremlin.driver.ser.AbstractMessageSerializer.lambda$addioRegistries$0(AbstractMessageSerializer.java:63)

Caused by: java.lang.classNotFoundException: org.janusgraph.graphdb.tinkerpop.JanusGraphIoRegistry

添加以下依赖项后，代码会向 java.utils 提供以下列表中的一些错误：

    <dependency>
            <groupId>org.janusgraph</groupId>
            <artifactId>janusgraph-core</artifactId>
            <version>0.5.3</version>
     </dependency>

Errors : few of them are
The package java.util is accessible from more than one module: <unnamed>,java.base
CompletableFuture cannot be resolved to a type
Description Resource    Path    Location    Type
List cannot be resolved to a type
UUID cannot be resolved

不知道如何在 java11 上解析 addV / addE 的结果。

任何示例都会有所帮助。

谢谢
