Question

我开始学习使用java9 Jigsaw的新功能。

我遵循this tutorial并设法创建一个包含两个模块和外部模块依赖项的项目。（我发布下面的pom文件代码以给出产品结构的概念）

现在我想在Eclipse Oxygen中导入我的maven项目（带有Java9插件支持），以便在Eclipse IDE中运行和调试项目。

我使用Oxygen.1a并且我为Oxygen 4.7安装了Java 9支持

我使用“Import Existing Maven project”，然后选择root pom.xml。

Everithing工作得很好我有我的项目导入其中两个被认为是Java项目（jsaw-date-cli和jigsaw-date-server），而根模块被认为是一个简单的m2项目。

现在我尝试使用常见的Ran作为Java Appliocation从eclipse运行jsaw-date-cli Main“但我已经修改了：

Error occurred during initialization of boot layer
java.lang.module.FindException: Module jigsaw.date.cli not found

如何配置项目以使cli项目自己的模块在运行时可用？我打开正确导入外部模块的构建路径属性！

我尝试在“RunConfiguration”中添加

来设置模块

/maven-build/target/modules

作为ModulePath条目但结果相同。

我还尝试添加VM命令行参数：

--module-path  ${workspace_loc:maven-build}/target/modules/

但错误仍然存在。

我可以使用

从命令行运行项目

java -jar --module-path target/modules -m jigsaw.date.cli

但我想从eclipse运行并调试它！

Answer 1

我终于设法使用eclipse运行项目并使用调试器，无需删除或添加任何插件。

我只是在运行配置中添加广告VM argument：

--module-path  ${workspace_loc:maven-build}/target/modules/ -m jigsaw.date.cli/com.javacodegeeks.jigsaw.date.cli.Main
