无法使用maven导入库

Unable to import library with maven

我正在尝试使用 Maven 导入 Ripple Effect 库 https://github.com/traex/RippleEffect

它说 "The lib is available on Maven Central, you can find it with Gradle, please"。我不知道 Gradle 是什么,它的信息 (http://gradleplease.appspot.com/#rippleeffect) 对我一点帮助都没有。

我找到了如何使用 maven 导入它。我将此依赖项添加到我的 POM 中:

<dependency>
            <groupId>com.github.traex.rippleeffect</groupId>
            <artifactId>library</artifactId>
            <version>1.3</version>
        </dependency>

并确保我有 Maven 中央存储库:

<repository>
            <id>central</id>
            <name>Maven Repository Switchboard</name>
            <layout>default</layout>
            <url>http://repo1.maven.org/maven2</url>
            <releases>
                <updatePolicy>always</updatePolicy>
            </releases>
            <snapshots>
                <enabled>false</enabled>
            </snapshots>
        </repository>

但是,当我尝试 运行 项目时,它显示:

Failed to execute goal on project ProjectName: Could not resolve dependencies for project lt.adnera:ProjectName:apk:0.0.1-SNAPSHOT: Failure to find com.github.traex.rippleeffect:library:jar:1.3 in http://repo1.maven.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced 

有什么想法吗?

根据http://repo1.maven.org/maven2/com/github/traex/rippleeffect/library/1.3/library-1.3.pom包装是aar所以没有可以下载的jar。 尝试:

<dependency>
    <groupId>com.github.traex.rippleeffect</groupId>
    <artifactId>library</artifactId>
    <version>1.3</version>
    <type>aar</type>
</dependency>
