AspectJ在跟踪源文件中的注释时出错

Question

I have an aspect code like this:

package aspects;

import java.util.logging.Level;
import java.util.logging.Logger;

import org.aspectj.lang.Signature;
import org.junit.Test;

public aspect TestCaseTrace{

    // pointcut traceTestCase() : (execution(public * test*(..)));

    pointcut traceTestCase() : (execution(@Test * *(..)));

    before(): traceTestCase(){
        String sourceName = thisJoinPointStaticPart.getSourceLocation().getWithinType().getCanonicalName();
        Signature sig = thisJoinPointStaticPart.getSignature();
        System.out.println("Test case name is " + sig.getDeclaringTypeName() + "." + sig.getName() + "\n\n");
    }

    after(): traceTestCase(){
    // Logger.getLogger("Tracing").log(Level.INFO,"Test case got over\n\n");
        System.out.println("Test case got over\n\n");
    }
}

I'm trying to trace the junit @Test in the above code. While I compile the aspect, with the below command:

ajc -classpath aspectjrt.jar:junit-4.10.jar  -outxml -outjar aspects.jar  TestCaseTrace.java

but this command gives an error like this:

TestCaseTrace.java:13 [error] annotation type patterns are only supported at Java 5 compliance level or above
pointcut traceTestCase() : (execution(@Test * *(..)));


1 error

where I'm making the mistake?

Java version used is 1.7 and aspect version is 1.8.6

Edit:

After following the answer I could able to compile with warnings. But after that if I use the resulting aspect.jar to inspect the junit test case:

import org.junit.Test;
class HelloWorldApp {

    @Test
    public void testSome()
    {
        A.methodA();
    }

}


class A{
    public static void methodA()
    {
        methodB();
    }

    public static void methodB()
    {

    }
}

and run with the command line:

java -javaagent:aspectjweaver.jar -cp aspects.jar:. HelloWorldApp

Nothing is getting printed.

The default compliance level of the AspectJ compiler is independent of the version of the Java runtime. The default (ajc) is Java 1.4, as is specified in the documentation :

Set compliance level to 1.4 (default) This implies -source 1.4 and -target 1.2.

Thus, if you aspects need a higher compliance version, you need to specify the version explicitly when calling ajc :

ajc -classpath aspectjrt.jar:junit-4.10.jar -1.5 -outxml -outjar aspects.jar  TestCaseTrace.java
                                            ^^^^ you need this
