Question

我在JDK 9上使用Ignite时遇到问题。我有以下最小的测试用例：

package no.ovstetun.ignite;

import org.apache.ignite.spi.discovery.tcp.TcpDiscoverySpi;
import org.junit.Test;

public class FailingIgniteTest {
    @Test
    public void failingIgnite() {
        TcpDiscoverySpi discoverySpi = new TcpDiscoverySpi();
    }
}

此代码示例失败，显示以下堆栈跟踪：

我正在尝试将我的代码库迁移到Java 8之外，而Ignite现在是阻止我的唯一依赖。我尝试将--add-module添加到我的跑步者，但我似乎无法找到使Ignite与JDK 9一起工作所需的内容。

与Ignite版本2.4.0和2.5.0相同的错误。

非常感谢任何帮助！

Answer 1

尝试在启动Java时添加以下参数：

.select-organization > a:nth-child(1)

Answer 2

作为VM参数的替代方法，您可以在库的META-INF / MANIFEST.MF中指定--add-exports：

Add-Exports: java.base/jdk.internal.misc
