android - robolectric 的 Maven 依赖范围要么停止测试运​​行，要么使构建耗尽堆空间

Question

我有这个 Android 项目，并且在使用 Maven 和 Robolectric 配置构建时遇到了一些困难。如果我将 robolectric 依赖项的范围设置为“测试”，则项目构建良好，但测试无法运行 [junit 或 java.lang.NoClassDefFoundError 的错误版本]。如果我不设置 robolectric 依赖项的范围，则测试运行良好（并通过），但构建用完了堆空间。

我是 Maven 新手，可能做错了什么。

我的依赖项看起来像这样::

    <dependency>
        <groupId>com.google.android</groupId>
        <artifactId>android</artifactId>
        <version>${platform.version}</version>
        <scope>provided</scope>
    </dependency>

    <dependency>
        <groupId>org.robolectric</groupId>
        <artifactId>robolectric</artifactId>
        <version>2.0-alpha-1</version>
        <scope>test</scope>
    </dependency>

    <dependency>
        <groupId>junit</groupId>
        <artifactId>junit</artifactId>
        <version>4.8.2</version>
        <scope>test</scope>
    </dependency>

    <dependency>
        <groupId>com.j256.ormlite</groupId>

    </dependency>

    </dependency>

    <dependency>

        <artifactId>ormlite-jdbc</artifactId>

    </dependency>

    <dependency>

        <artifactId>mockito-all</artifactId>

        <scope>test</scope>
    </dependency>

    <dependency>

        <artifactId>robolectric</artifactId>
        <version>2.0-rc2</version>

    </dependency>

</dependencies>

任何关于这里发生的事情的智慧都将被感激地接受并立即投入使用:)

这是根据 Matt 的建议更新后的完整 pom.xml。（下）不幸的是，问题仍然存在。

所以..更新了插件依赖版本并运行 mvn 'clean' & 'install' 以及问题仍然存在。运行 robolectric 测试给出以下输出 >>

进一步调查 >

这个链接 显示了包含操作码的 jars，我添加了我在这里找到的这个依赖项

<dependency>
    <groupId>asm</groupId>
    <artifactId>asm-all</artifactId>
    <version>2.2</version>
</dependency>

我已将此添加为 pom 中的第一个依赖项，但我仍然为 OpCodes 获得 NoClassDefFound。

终于找到了一些似乎有效的东西:: 已添加<classifier>jar-with-dependencies</classifier>到 robolectric 依赖项中，测试最终运行。

我看你有

<dependency>
    <groupId>org.robolectric</groupId>
    <artifactId>robolectric</artifactId>
    <version>2.0-alpha-1</version>
    <scope>test</scope>
</dependency>

接着

<dependency>
    <groupId>org.robolectric</groupId>
    <artifactId>robolectric</artifactId>
    <version>2.0-rc2</version>
    <scope>test</scope>
</dependency>

我不相信您可以像这样列出两次相同的依赖项并编译应用程序，但我可能错了。

尽管如此，尝试更新一些依赖版本。我成功地使用了 junit 4.10，以及 robolectric 2.1（当我使用它时，2.0 也能正常工作），然后 mockito 也在 1.9.5。

我建议检查 maven Central 以获取最新的依赖项。我相信 jUnit 4.11 和 robolectric 之前存在问题，所以我还没有尝试将其升级到 4.11。
