IceRevenge：

私は、依存関係Unirestをインストールするには、Mavenを使用しようとしました。私は、.jarファイル（ダウンロードunirest-javaの-1.4.9.jarを）そして、このようなPOMにこれを追加しました：

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>com.mashape.unirest</groupId>
            <artifactId>unirest-java</artifactId>
            <version>1.4.9</version>
        </dependency>
    </dependencies>
</dependencyManagement>

また、私は、Eclipseでの.jarを追加しました： Eclipseの

今Mavenはパッケージが存在しないことを言います。Eclipseは、何かが間違っていたことを言いませんでした。私は間違って何をしたのですか？警告は、最初に問題がありますか？
