Question

My Maven项目使用外部库作为依赖项com.sk89q.intake:intake，我正试图通过maven-shade-plugin打包到我的jar中。构建项目时，生成的jar不包含com.sk89q.intake:intake的任何类文件。在构建过程中，我收到此消息，但构建继续并成功：

[INFO] --- maven-shade-plugin:2.4.2:shade (default) @ EventManagerPlugin
[INFO] No artifact matching filter com.sk89q.intake:intake

为什么会这样？我能够在项目中下载，访问和使用依赖项，因此对工件的命名应该没有任何问题。

的pom.xml

如您所见，我包含com.sk89q.intake:intake神器。我查看了maven-shade-plugin文档，看不出我做错了什么。命名与我在网上找到的所有内容一致;也就是groupId:artifactId。

我还尝试在没有<relocation>类重定位标记的情况下构建，以查看它们是否在干扰。

知道我正在使用M2Eclipse并建立clean install目标可能很有用。

问题在于您宣布与com.sk89q.intake:intake范围的provided依赖关系。

预计容器会在运行时提供依赖关系，因此maven-shade-plugin不会将其添加到您的着色jar中。因此，您需要从依赖项声明中删除provided范围：

<dependency>
    <groupId>com.sk89q.intake</groupId>
    <artifactId>intake</artifactId>
    <version>4.2-SNAPSHOT</version>
</dependency>

此更改后的相关构建日志：

[INFO] --- maven-shade-plugin:2.4.2:shade (default) @ test ---
[INFO] Including com.sk89q.intake:intake:jar:4.2-SNAPSHOT in the shaded jar.
[INFO] Including com.google.guava:guava:jar:18.0 in the shaded jar.
[INFO] Including com.google.code.findbugs:jsr305:jar:3.0.0 in the shaded jar.

Maven shade插件没有将依赖类文件放入jar
