AspectJ Maven 插件破坏了 GMaven 构建的 Groovy 类答案

【问题标题】：AspectJ Maven plugin corrupting Groovy classes built by GMavenAspectJ Maven 插件破坏了 GMaven 构建的 Groovy 类
【发布时间】：2011-04-04 23:08:38
【问题描述】：

我试图在一个模块上运行 Groovy 和 AspectJ，但是当我添加 AspectJ 时，这些类返回的值似乎与我预期的非常不同：

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>

这不是我所期望的，当我关闭 AspectJ 时，一切正常。

    Results :

    Tests run: 30, Failures: 0, Errors: 0, Skipped: 0

    ...

这是我的 AspectJ 插件，它似乎是导致问题的原因：

        <plugin>
            <groupId>org.codehaus.mojo</groupId>
            <artifactId>aspectj-maven-plugin</artifactId>
            <version>1.3.1</version>

                    </goals>

            </executions>
            <configuration>
                <complianceLevel>1.6</complianceLevel>
            </configuration>
        </plugin>

但是当我启用 aspectj-maven-plugin 时，一切都开始失败：

    [ERROR] There are test failures.

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

这是 Groovy 测试：

    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);
        }
    }

然后我也创建了一个 Java 单元测试用例：

    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);
        }
    }

谁能帮我理解为什么 aspectj-maven-plugin 似乎会导致我的最终字节码出现编译错误？

【问题讨论】：

如果我们看不到测试代码，那么显示测试的输出并没有多大意义
更新了 Groovy 和 Java 测试用例。
您没有编译但测试失败。如果您认为它们是由 AspectJ Maven 引起的，您是否使用了任何方面？如果是这样，你能告诉我们方面代码吗？请提供SSCCE 以使问题可重现。我在下面的回答只是一个建议，如果我看到你的代码，我只能确定它会有所帮助。

【解决方案1】：

我对 GMaven 的体验一直很差。一旦我切换到 Gradle，大部分“怪异”就消失了。这听起来像是你不想在 GMaven 上浪费时间的那种怪事。

【讨论】：

【解决方案2】：

我认为切换到 Gradle 不是一种解决方案，而是一种代价高昂的解决方法，尤其是对于大型项目而言。所以我不同意Mike Wazowski。也许你应该修复你的 Maven 设置。您可以做几件事：

首先，AspectJ Maven 1.3.1 来自 2011 年，使用了一个非常旧的 AspectJ 版本 (1.6.10)。为什么不升级到默认使用 AsepctJ 1.8.2 的 AspectJ Maven 1.7？您甚至可以将它升级到包含更多错误修复的最新版本 AspectJ 1.8.6？
您也可以考虑从 GMaven 切换到 GMavenPlus，因为前者不再维护 AFAIK，而后者是。
顺便说一句，您也可以从 Java 6 切换到 8 或至少 7，因为不再维护 Java 6。

我的 AspectJ Maven 设置通常看起来像这样（我在这里省略了 GMaven 设置）：

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