错误：（226、34）java：找不到符号符号：变量 BodyPublisher 位置：类 jdk.incubator.http.HttpRequest

private static JSONObject sendRequest(JSONObject json) throws Exception {
    HttpClient client;
    InetSocketAddress proxy = getRandomProxy();

    if(proxy == null) {
        client = HttpClient.newHttpClient();
    } else {
        client = HttpClient.newBuilder().proxy(ProxySelector.of(proxy)).build();
    }

    HttpRequest httpRequest = HttpRequest
            .newBuilder(new URI(BASE_URL))
            .header("Accept", "application/json")
            .header("Content-Type", "application/json")
            .timeout(TIMEOUT_DURATION)
            .POST(HttpRequest.BodyPublisher.fromString(json.toString()))
            .build();

    HttpResponse<String> httpResponse = client.send(httpRequest, HttpResponse.BodyHandler.asString());
    String jsonResponse = httpResponse.body();

    return new JSONObject(jsonResponse);
}

模块信息.java：

module MyProject {

    requires jdk.incubator.httpclient;

}

我已经在 Linux 上使用 OpenJDK 10 和 Oracle JDK 10 进行了尝试。

您可以检查模块的目标字节码版本（File > Settings > Build, Execution, Deployment > Compiler> Java Compiler），它应该设置为 10。您还可以在File > Project Settings下检查项目 SDK 和语言级别设置> 项目和文件 > 项目设置 > 模块。
