Question

从昨天开始，我收到一个奇怪的类路径错误-升级JDK之后：

IEnumerable<T>.ForEach

但是，在IntelliJ中它可以正常工作。有关详细信息，请参见配置：

ForEach

可以在https://github.com/geoHeil/classpath-gradle-test-failures/blob/master/build.gradle处找到详细的配置：

git clone
等级考试

java版本：

*NoClassDefFoundError*: org/apache/hadoop/hive/ql/session/SessionState when creating Hive client using classpath: file:/Users/geoheil/project/build/classes/java/test, file:/Users/geoheil/project/build/classes/scala/test/
    Please make sure that jars for your version of hive and hadoop are included in the paths passed to spark.sql.hive.metastore.jars.

项目编译步骤中的警告提示已使用Java 9+。有关新模块系统的详细信息，请参见此SO answer。

设置了Java 8后，您的演示项目就可以正常运行，而Java 10会因您所描述的错误而失败。对于任何JDK 9+版本，我都会期望同样的错误。

Oracle JDK 8（1.8.0_181）：

JDK 10（10.0.2）：
