Maven 在使用测试 scope 时无法编译测试类

[英]Maven cant compile test-classes when using test scope

问题描述

我目前正在尝试使用MockBukkit来测试我的 Minecraft 插件，并将它包含在我的 pom 中并通过测试 scope 因为我只需要它。 然而问题是，当使用测试 scope 时，依赖项出现在我的本地存储库中，但无法通过 eclipse 或 Maven 解决。

问题似乎是编译器插件的默认编译目标试图编译测试类，即使它不能使用依赖项，因为它们仅在测试阶段可用。 （但这只是我的猜测）。

好的，错误只是我必须更改.classpath，因为我刚刚将默认的 eclipse 项目转换为 Maven 项目，所以我不得不删除构建路径中的默认 src 文件夹并添加不同的 Z91175C109804AC13777F744C 文件夹。 没有它，Maven 试图将每个 class 编译为正常的，而不是作为使它们失败的测试。

如果有人感兴趣，这里是两个.classpath 文件之间的比较：

老的：

<?xml version="1.0" encoding="UTF-8"?>
<classpath>
    <classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER">
        <attributes>
            <attribute name="module" value="true"/>
            <attribute name="maven.pomderived" value="true"/>
        </attributes>
    </classpathentry>
    <classpathentry including="**/*.java" kind="src" output="target/classes" path="src">
        <attributes>
            <attribute name="optional" value="true"/>
            <attribute name="maven.pomderived" value="true"/>
        </attributes>
    </classpathentry>
    <classpathentry kind="con" path="org.eclipse.m2e.MAVEN2_CLASSPATH_CONTAINER">
        <attributes>
            <attribute name="maven.pomderived" value="true"/>
        </attributes>
    </classpathentry>
    <classpathentry kind="output" path="target/classes"/>
</classpath>

新的：

<classpath>
    <classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER">
        <attributes>
            <attribute name="module" value="true"/>
            <attribute name="maven.pomderived" value="true"/>
        </attributes>
    </classpathentry>
    <classpathentry kind="src" path="src/main/java"/>
    <classpathentry kind="src" output="target/test-classes" path="src/test/java">
        <attributes>
            <attribute name="test" value="true"/>
        </attributes>
    </classpathentry>
    <classpathentry kind="src" path="src/main/resources"/>
    <classpathentry kind="con" path="org.eclipse.m2e.MAVEN2_CLASSPATH_CONTAINER">
        <attributes>
            <attribute name="maven.pomderived" value="true"/>
        </attributes>
    </classpathentry>
    <classpathentry kind="output" path="target/classes"/>
</classpath>
