AspectJ Maven插件破坏GMaven构建的Groovy类

我试图在一个模块上运行Groovy和AspectJ，但当我添加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>

下面是我的AspectJ插件，它似乎导致了这个问题：

        <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>

然后我还创建了一个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);
        }
    }

有人能帮我理解为什么aspectj maven插件会导致我的最终字节码出现编译错误吗？

我使用GMaven的经验很差。一旦我转到格拉德尔，许多“古怪”就消失了。这听起来有点奇怪，你不想在GMaven上浪费时间。

我认为切换到Gradle不是一个解决方案，而是一个昂贵的解决方案，尤其是对于大型项目。所以我不同意迈克·瓦佐夫斯基的观点。也许你应该修复你的Maven设置。您可以做以下几件事：

• 首先，AspectJ Maven 1.3.1从2011年开始发布，并使用非常旧的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？您甚至可以将其升级到AspectJ 1.8.6，这是包含更多错误修复的最新版本

<>你也可以考虑从GMAVEN切换到GMAVEPLUS，因为前者不再是主要的，而后者是
。
• 顺便说一句，您也可以从Java6切换到8或至少7，因为Java6不再维护

我的AspectJ Maven设置通常是这样的（我在这里省略了GMaven设置）：

UTF-8
1.8
1.8.6
org.apache.maven.plugins
maven编译器插件
3.1
${java.source-target.version}
${java.source-target.version}
假的
org.codehaus.mojo
aspectj maven插件
1.7
真的
${java.source-target.version}
${java.source-target.version}
忽视
${java.source-target.version}
UTF-8
真的
过程源
编译
测试编译
org.aspectj
aspectjtools
${aspectj.version}
org.apache.maven.plugins
maven编译器插件
org.codehaus.mojo
aspectj maven插件
org.aspectj
aspectjrt
${aspectj.version}
运行时
org.aspectj
aspectjrt

如果我们看不到使用Groovy和Java测试用例更新的测试代码，那么显示测试输出就没有什么意义了。您没有编译，只有测试失败。如果您认为它们是由AspectJ Maven引起的，您是否使用了任何方面？如果是的话，你能给我们看一下方面代码吗？请提供一份报告，以使问题重现。我下面的答案只是一个建议，我只能确定，如果我看到你的代码，它会有所帮助。
