如何在 Java、JDK17、"module-info.java"、Netbeans、Maven 上 "require" 模块 "gwt.user"
How to "require" module "gwt.user" On Java, JDK17, "module-info.java", Netbeans, Maven
我正在努力跟上 Java 中的新变化,一步一个脚印。
我正在用 module-info.java 文件更新我的旧库。
我有一个非常简单的项目,名为“api-clone”,依赖于“gwt-user”。

使用以下模块-info.java:
open module com.tugalsan.api.clone {
requires gwt.user;
}
netbeans 运行编译时,构建成功:
cd C:\me\codes\GWT\api\api-clone; "JAVA_HOME=C:\Program Files\Eclipse Adoptium\jdk-17.0.2.8-hotspot" cmd /c "\"C:\Program Files\NetBeans-13\netbeans\java\maven\bin\mvn.cmd\" \"-Dmaven.ext.class.path=C:\Program Files\NetBeans-13\netbeans\java\maven-nblib\netbeans-eventspy.jar\" -Dfile.encoding=UTF-8 clean install"

但是,当我查看 module-info.java 文件时,Netbeans 显示错误:
- 是不是因为“gwt.user”不是模块化项目?
- 当项目依赖于它们时,如何处理此类项目?
正如@skomisa 回答的那样,我在“module-info.java”中面临的问题
可以在“pom.xml”中通过在依赖标签上添加排除来解决。
