主 java 模块有这种问题.

我知道出了什么问题，但是除了从主模块中删除 module-info.java 之外，还有什么解决方法吗?

解决方案

如果你确实理解了错误，详细阅读以下内容:

<块引用>

模块 java.naming 不会将 com.sun.jndi.ldap 导出到模块spring.ldap.core

然后，您可以为此制定解决方法，以通过命令行使用修饰符作为 JVM 选项提供访问:

--add-exports java.naming/com.sun.jndi.ldap=spring.ldap.core

Had this kind of problem with main java module.

Process finished with exit code 1

I understand whats wrong, but is there any workaround for this, besides remove module-info.java from main module ?

解决方案

If you do understand the error specifically when it reads in details the following:

module java.naming does not export com.sun.jndi.ldap to module spring.ldap.core

You can then formulate the workaround for this to provide access using modifiers as JVM options via the command line:

--add-exports java.naming/com.sun.jndi.ldap=spring.ldap.core
