Question

我正在使用Eclipse来编译带有aspectj的java代码。我的代码（与方面）工作正常，但我正在构建我的代码的jar文件。

例如，如果我选择导出＆gt; Runnable JAR文件，在组合框中我没有看到我的项目（所有其他不基于aspecj的项目都显示在组合框中）。

如果您希望具有可在命令行以及Eclipse或IntelliJ IDEA等IDE中运行的可重复构建，我建议使用Maven构建。 onejar-maven-plugin 为您创建一个可运行的JAR，包括AspectJ运行时和所有其他声明的依赖项：

Answer 2

尝试使用与AspectJ运行配置相同的启动类创建正常运行配置。创建可运行的JAR时，请选择正常运行配置。生成的JAR将具有AspectJ支持。

Answer 3

runnable jar exporter only works with Java Application type launch configs，但这应该不是问题。使用主类创建正常的{{1}}启动配置，并根据新创建的启动配置导出可运行的jar。它应该工作。

如何使用AspectJ创建可运行的jar文件？
