Why open a non-existing package from a Java module?

问题 The JLS 11 "7.7.2. Exported and Opened Packages" says: It is permitted for opens to specify a package which is not declared by a compilation unit associated with the current module. What would be a scenario for this? Why is this needed? 回答1: Thanks to Alan Bateman and Michael Easter for explanations, and I can think of some realistic scenarios. First, as was explained by Alan and Michael: JLS allows to "open" directories without Java types for situations when we keep resources in them. So,

How to export all packages from Java 9 module? [duplicate]

问题 This question already has an answer here : Why is exporting the entire module not allowed? (1 answer) Closed 2 years ago . Right now, for every module I have, I need to explicitly specify packages I want to export. For example: module core { exports cc.blynk.server.core; exports cc.blynk.server.core.protocol.handlers.decoders; exports cc.blynk.server.core.protocol.handlers.encoders; } However, it is not very convenient. I would like to do something like that: module core { exports cc.blynk

Can one Java module export a package whose name is a subpackage of a package from another module? [duplicate]

This question already has an answer here : Java 9 sub-packages split across modules (1 answer) Closed 10 months ago . So I know that, in Java 9 modules (Project Jigsaw), split packages are not allowed. That is, the following modules couldn't both export a package with the same name and also be used at the same time at run time: Module 1 module com.example.foo { exports com.example.foo; } Module 2 module com.example.foo { exports com.example.foo; } Not allowed (or, at least, they can't run at the same time). But what isn't clear to me is how subpackages come in to play. If one module exports

I'm adding module-info.java s to Ikonli packages and I'm running into trouble with their service classes. ikonli-core defines an interface called IkonHandler . ikonli-fontawesome5-pack has a service provider for the IkonHandler called FontAwesomeSolidIkonHandler . These service prodivers are used by ikonli-javafx 's IkonResolver . Given this, I created these module definitions: module org.kordamp.ikonli.core { exports org.kordamp.ikonli; } module org.kordamp.ikonli.javafx { exports org.kordamp.ikonli.javafx; uses org.kordamp.ikonli.IkonHandler; requires javafx.graphics; requires org.kordamp

Best approach to dynamically load modules (classes) in Java

由 不问归期 提交于 2019-12-06 00:54:45
问题 I'm currently writing an application that requires to operate on different type of devices. My approach would be to make a "modular" application that can dynamically load different classes according to the device they need to operate on. To make the application easily extensible, my goal is to assign a specific path to the additional modules (either .jar or .class files) leaving the core program as it is. This would be crucial when having different customers requiring different modules

Java9 JNLP --add-opens not working

问题 I have created a simple test case to test Java 9 Web Start with the new modules. Unfortunately, Java 9 Web Start does not by default support --permit-illegal-access like regular Java 9 does. Java 9 Web Start is suppose to support --add-opens (see https://bugs.openjdk.java.net/browse/JDK-8172986). I'm using Java 1.9.0_181_ea. Here is my test class: import java.awt.Toolkit; import java.lang.reflect.Method; import java.lang.IllegalAccessException; import java.lang.reflect
