在Maven和Java 9中将第三方工件与拆分包一起使用 [英] Use third party artifacts with split packages in Maven and Java 9

问题描述

我试图使我的项目适合Java 9，并且遇到拆分包(共享同一包的工件)问题.

I am trying to make my project ready for Java 9 and I am running into problems with split packages (artifacts sharing the same package).

我的应用程序至少依赖于两个第三方遗留工件(它们是使用Java< 9构建的).当我使用Java 9运行Maven时，我得到:

My application depends on at least two third-party legacy artifacts (that are built with Java <9). When I run Maven with Java 9, I get:

[ERROR] module myapp reads package P from both A and B

这是正确的，因为包P存在于A.jar和B.jar中，但没有重叠的类.我了解这是Java 9的问题，我在--patch-module <package>=<path-to-jar>). 在此处还有另一种想法，

Which is correct, since the package P exists in A.jar and B.jar, but without overlapping classes. I understand that this is a problem for Java 9 and I studied suggested solutions in https://blog.codefx.org/java/java-9-migration-guide/#fixes-2 . To summarize it is either "Fix your code" (not possible, since third-party JAR) or "Run with command line options" (Where the most interesting may be --patch-module <package>=<path-to-jar>). There was another idea here, which said

将第3方模块之一(或两者)包装在一个简单的模块中，该模块仅执行显式导出模块实际需要的程序包，什么都不做.

wrap one of the 3rd party modules (or both) in a simple module, which does nothing but explicitly exports only the package(s) that are actually needed by your module.

但是我如何在Maven(3.5.0)中实现此目标，目前我只拥有一个<dependency>和maven-compiler-plugin:3.7.0-我不想静态地重新打包第三方JAR?

But how can I achieve this in Maven (3.5.0), where all I currently have is a <dependency> and the maven-compiler-plugin:3.7.0 - and I don't want to statically repackage third party JARs?

欢迎提供任何示例提示或提示.

Any hint or pointer to an example would be welcome.

示例为我工作:

<Export-Package>
  org.hibernate.*;version=${pkgVersion};-split-package:=merge-last                       

</Export-Package>
