Java 9模块，NoClassDefFoundError:java.sql.Date [英] java 9 modules, NoClassDefFoundError: java.sql.Date

问题描述

我试图用Java 9运行我们的Java 8 gradle项目，因为我们希望迁移到该项目.但是，在执行单元测试时，我得到了

I tried running our java 8 gradle project with java 9, since we are looking to migrate to it. However, when executing a unit test I get a

java.lang.ClassNotFoundException: java.sql.Date例外

由com.fasterxml.jackson.databind.deser.std.DateDeserializers

在代码中看起来像这样:

Looks like this in code:

static {
    Class<?>[] numberTypes = new Class<?>[] {
        ...
        java.sql.Date.class,
        ...
    };
    ...
}

我在互联网上四处张望，显然，如果您想避免为每个模块制作一个module-info.java文件，则必须添加参数--add-modules java.sql.

I have looked around on the internet, and apparently, if you want to avoid making a module-info.java file for every module, you have to add the parameter --add-modules java.sql.

我正在使用intellij，并且已将参数添加到File>Settings>Build,Execution,Deployment>Compiler>Java Compiler中的javac参数中，并且还在以虚拟机方式运行的配置中添加了该参数，但是仍然出现异常.

I am using intellij, and have added the parameter to the javac arguments in File>Settings>Build,Execution,Deployment>Compiler>Java Compiler and also in the run config as VM option, but I still get an exception.

是否有更简单的方法来执行此操作，或者我做错了什么? 谢谢

Is there an easier way to do this, or what am I doing wrong? Thanks

IntelliJ版本:

推荐答案

在我删除了jdk9并重新添加它之后，该问题得以解决.

The issue fixed itself after I removed the jdk9 and re-added it.
