Question

我正在使用这个Maven脚本构建我的应用程序。但后来我收到了一大堆错误（见帖子末尾）。就好像找不到 android.jar 一样。我检查了 android.jar 的路径，没关系。

Answer 1

问题只是<dependencyManagement>标签不应该在那里。

Answer 2

这一行：C：\ dev \ android-sdk-windows \ platforms \ android-4 / tools / aapt

你确定那是对的吗？这可能是android.jar没被拿起的原因..

Answer 3

我无法重现您的错误。但是对我来说，使用android.jar for 2.1.2（平台7）并指定平台4（Android 1.6）似乎很奇怪。如果你想让你的应用程序在1.6上运行，你应该使用1.6中的android.jar。因为这是在运行时可用的。

        <dependency>
            <groupId>com.google.android</groupId>
            <artifactId>android</artifactId>
            <version>1.6_r2</version>
            <scope>provided</scope>
        </dependency>

如果你想使用平台8（Froyo）附带的AndroidManifest.xml的功能，比如installLocation，你不应该使用平台4而是8。

       <plugin>
            <groupId>com.jayway.maven.plugins.android.generation2</groupId>
            <artifactId>maven-android-plugin</artifactId>
            <configuration>
                <sdk>
                    <path>${env.ANDROID_HOME}</path>
                    <platform>8</platform>
                </sdk>
                <deleteConflictingFiles>true</deleteConflictingFiles>
            </configuration>
            <extensions>true</extensions>
        </plugin>

如果您使用Maven＆gt;版本2.0.9（IIRC）您不必再指定插件的版本。然后自动使用最新版本。
