Question

在Maven中，我正在尝试使用单元测试（使用maven-surefire-plugin）构建我的自定义插件，但是我收到以下错误：

重要的是：

junit.framework.AssertionFailedError: Maven 3.2.4 or better is required

但是当我查看版本时，我看到了：

$ mvn -version
Apache Maven 3.2.5

如果我使用-DskipTests跳过测试，那么它的构建正常。为什么会发生这种错误？也许我使用的依赖是Maven 3.2.5？为什么它没有检测到正确的版本？

任何帮助/建议都会非常有用。

P.S。在我添加了一个特定的mojo之后，这个错误就开始了。如果我删除了Mojo，它正在建设中。 Mojo可能会导致什么？

我从Setup()删除了dddTest.java，但我仍然遇到同样的错误，只是没有指定该行。新错误：

有什么想法吗？

<小时/> 编辑2：

我看到问题Django Documetation并且我意识到依赖版本存在一些问题。所以我更新了链接上提到的maven依赖项的版本，然后更新了一些（基于将依赖树与maven中心进行比较）。每次更新版本时，错误都会更改（但在测试期间仍会发生）。现在我面临以下错误：

java.lang.NoSuchMethodError: org.codehaus.plexus.ContainerConfiguration.setClassPathScanning(Ljava/lang/String;)Lorg/codehaus/plexus/ContainerConfiguration;

关于我应该更改哪个依赖版本的任何建议？

Answer 1

我使用以下依赖项工作：

...
<properties>
    <maven.version>3.5.0</maven.version>
</properties>
...
<dependencies>
    ...
    <dependency>
        <groupId>org.apache.maven</groupId>
        <artifactId>maven-plugin-api</artifactId>
        <version>${maven.version}</version>
    </dependency>
    <dependency>
        <groupId>org.apache.maven</groupId>
        <artifactId>maven-core</artifactId>
        <version>${maven.version}</version>
    </dependency>
    <dependency>
        <groupId>org.apache.maven.plugin-testing</groupId>
        <artifactId>maven-plugin-testing-harness</artifactId>
        <version>3.3.0</version>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>org.apache.maven</groupId>
        <artifactId>maven-aether-provider</artifactId>
        <version>3.3.9</version>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>org.apache.maven</groupId>
        <artifactId>maven-compat</artifactId>
        <version>${maven.version}</version>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>org.apache.maven</groupId>
        <artifactId>maven-model</artifactId>
        <version>${maven.version}</version>
        <scope>test</scope>
    </dependency>
    ...
</dependencies>
...

基于Vincent Zurczak的博客文章：https://vzurczak.wordpress.com/2014/07/23/write-unit-tests-for-a-maven-plug-in/

当我将org.apache.maven:maven-core的范围设置为 test 时，就像在Zurczak的示例中一样，它打破了构建，因为我在org.apache.maven.project.MavenProject中使用了.gitignore我的魔力。
