java – 有没有办法在使用maven-jlink-plugin时添加maven依赖项？

Error: module-info.class not found for joda.time module

我正在尝试使用它作为概念证明,我可以使用新的链接阶段部署图像,但自然我需要能够具有外部依赖性,我需要使用maven(工作约束).

对mod-jar / pom.xml的更改

...
 <dependencies>
    <dependency>
      <groupId>joda-time</groupId>
      <artifactId>joda-time</artifactId>
      <version>2.9.9</version>
    </dependency>
  </dependencies>
...

MOD-罐/ module-info.java

module com.soebes.nine.jar {
  requires java.base;
  requires joda.time;
  exports com.soebes.example.nine.jar;
}

我真的很感激任何帮助.谢谢.

jlink tool does not support linking of automatic modules因为它们可以依赖于类路径的任意内容,这违背了自包含Java运行时的想法.

所以有两种方法可以解决这个问题： –

>(你没有拥有jar)暂时继续创建一个module-info.java [你可以use jdeps tool为它]并使用相应的编译类更新jar [使用jar工具],就像在Java 9下的项目一样.
>(您拥有依赖项)永久地将jar迁移到Java 9本身,在编译和打包之后它将由module-info.class组成.
