问题描述
我不能mvn 包 使用下面的最小样本.Eclipse(Mars.2 Release 4.5.2)编译和编织没有问题.
I Cannot mvn package with the minimal sample below. Eclipse (Mars.2 Release 4.5.2) compiles and weaves without a problem.
我需要做什么才能让它发挥作用?
What do I have to do to make it work?
输出:
[INFO] --- maven-compiler-plugin:3.1:compile (default-compile) @ test ---
[INFO] Changes detected - recompiling the module!
[WARNING] File encoding has not been set, using platform encoding Cp1252, i.e. build is platform dependent!

symbol: method doSomethingInjected()
示例类:
package test;
public class Foo {
public void bar() {
this.doSomethingInjected();
}
}
示例界面:
package test;
public interface Injectable { }
方面:
package test;
public aspect Injection {
declare parents : test..* implements Injectable;
public void Injectable.doSomethingInjected() {
System.out.println("done");
}
}
pom.xml(根据 aspectj-maven-plugin 使用文档的相关部分)

推荐答案
试试这个,它能让你的项目编译运行干净(我测试过):
Try this, it makes your project compile and run cleanly (I tested it):
