AspectJ Maven plugin corrupting Groovy classes built by GMaven

I am trying to run Groovy and AspectJ on a module but when I add AspectJ, the classes seem to return very diferent values than I expected:

junit.framework.ComparisonFailure: null expected:<2011-04-03> but was:<null>

testGetUnixDayFromDate(com.baselogic.chapter05.utils.DateUtilitiesTest)  Time elapsed: 0.016 sec  <<< FAILURE!
junit.framework.AssertionFailedError: expected:<0> but was:<15037>

testGetDateDifferenceInDays(com.baselogic.chapter05.utils.DateUtilitiesTest)  Time elapsed: 0 sec  <<< FAILURE!
junit.framework.AssertionFailedError: expected:<0> but was:<7>

This is not what I expected and when I turn the off AspectJ, this all runs fine.

    ...

Here is my AspectJ plugin that seems to be causing the issue:

        <plugin>
            <groupId>org.codehaus.mojo</groupId>
            <artifactId>aspectj-maven-plugin</artifactId>
            <version>1.3.1</version>
            <executions>
                <execution>
                    <goals>
                        <goal>compile</goal>
                        <goal>test-compile</goal>
                    </goals>
                </execution>
            </executions>
            <configuration>
                <complianceLevel>1.6</complianceLevel>
            </configuration>
        </plugin>

But when I enable aspectj-maven-plugin everything starts failing:

    [ERROR] There are test failures.

    Please refer to C:\usr\SYNCH\PACKT\3166\Chapters_Code\ch05\target\surefire-reports for the individual test results.

Here is the Groovy test:

    package com.baselogic.chapter05.utils

    import groovy.util.GroovyTestCase
    import java.util.Calendar
    import java.text.SimpleDateFormat

    class DateUtilitiesTest extends GroovyTestCase {
        protected void setUp() {
            super.setUp()
        }

        protected void tearDown() {
            super.tearDown()
        }

        public void testGetYesterdayDate() {
            Calendar calendar = Calendar.getInstance()
            calendar.add(Calendar.DATE, -1)
            SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd")
            String expected = format.format(calendar.getTime());

            String result = DateUtilities.getYesterdayDate()
            println(result)
            assertEquals(expected, result)
        }

        void testGetUnixDayFromDate() {
            java.text.SimpleDateFormat formatter = new java.text.SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
            java.util.Date date = (java.util.Date) formatter.parse("2011-03-03 23:59:59");
            assertEquals(DateUtilities.getUnixDayFromDate(date), 15037);
        }

        void testGetDateDifferenceInDays() {
            java.text.SimpleDateFormat formatter = new java.text.SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
            java.util.Date date1 = (java.util.Date) formatter.parse("2011-03-03 23:59:59");
            java.util.Date date2 = (java.util.Date) formatter.parse("2011-03-10 23:59:59");
            assertEquals(DateUtilities.getDateDifferenceInDays(date1, date2), 7);
        }
    }

Then I created a Java unit test case as well:

    package com.baselogic.chapter05.utils;

    import org.junit.Test;

    import static org.junit.Assert.assertEquals;

    import java.text.SimpleDateFormat;
    import java.util.Calendar;

    public class DateUtilitiesJavaTest {

        @Test
        public void testGetYesterdayDate() {
            Calendar calendar = Calendar.getInstance();
            calendar.add(Calendar.DATE, -1);
            SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd");
            String expected = format.format(calendar.getTime());

            String result = DateUtilities.getYesterdayDate();
            // Aspect DontWriteToTheConsole will complain:
            // System.out.println(result);
            assertEquals(expected, result);
        }

        @Test
        public void testGetYesterdayDateScala() {
            Calendar calendar = Calendar.getInstance();
            calendar.add(Calendar.DATE, -1);
            SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd");
            String expected = format.format(calendar.getTime());

            String result = ScalaDateUtilities.getYesterdayDate();
            assertEquals(expected, result);
        }
    }

Can anyone help me understand why the aspectj-maven-plugin seems to be causing compilation errors with my final bytecode?

My experience with the GMaven has been poor. Once I switched to Gradle, much of the 'weirdness' went away. This sounds like that kind of weirdness you don't want to waste time with GMaven.

I think that switching to Gradle is not a solution but an expensive workaround, especially for big projects. So I disagree with Mike Wazowski. Maybe you should just fix your Maven setup. There are several things you can do:

• First of all, AspectJ Maven 1.3.1 ist from 2011 and uses a very old AspectJ version (1.6.10). Why not upgrade to AspectJ Maven 1.7 which uses AsepctJ 1.8.2 by default? You can even upgrade it to AspectJ 1.8.6, the latest version containing more bugfixes?

• You could also consider switching from GMaven to GMavenPlus because the former is no longer mainained AFAIK, while the latter is.

• BTW, you could also switch from Java 6 to 8 or at least 7 because Java 6 is no longer maintained.

My AspectJ Maven setup usually looks something like this (I am omitting GMaven setup here):

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <java.source-target.version>1.8</java.source-target.version>
    <aspectj.version>1.8.6</aspectj.version>
</properties>
