java - Graphhopper 演示项目无法在 Android Studio 上运行

Question

我尝试在 Android Studio 上开发 Graphhopper 演示项目，我在这里找到了它:https://github.com/graphhopper/graphhopper/tree/master/android

Gradle 构建后我收到此错误:错误:无法解析:com.graphhopper:graphhopper:0.6-SNAPSHOT

现在 Android Studio 无法解析 Graphhopper 类的符号。

这是我的 build.gradle:

apply plugin: 'com.android.application'

android {
compileSdkVersion 19
buildToolsVersion "21.1.2"

defaultConfig {
    applicationId "com.graphhopper.android"
    minSdkVersion 10
    targetSdkVersion 22
}

buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
    }
}

lintOptions {
    /* CGIARProvider refers to java.awt
     * Helper7 refers to java.lang.management
     * HeightTile refers to javax.imageio and java.awt
     * OSMElement refers to javax.xml.stream
     */
    disable 'InvalidPackage'
}
}

/** only necessary if you need to use latest SNAPSHOT
configurations.all {
// check for updates every build
resolutionStrategy.cacheChangingModulesFor 0, 'seconds'
}
**/

dependencies {
compile(group: 'com.graphhopper', name: 'graphhopper', version: '0.6-SNAPSHOT') {
   exclude group: 'com.google.protobuf', module: 'protobuf-java'
   exclude group: 'org.openstreetmap.osmosis', module: 'osmosis-osm-binary'
   exclude group: 'org.apache.xmlgraphics', module: 'xmlgraphics-commons'
}

compile group: 'org.mapsforge', name: 'mapsforge-core', version: '0.5.2'
compile group: 'org.mapsforge', name: 'mapsforge-map', version: '0.5.2'
compile group: 'org.mapsforge', name: 'mapsforge-map-android', version: '0.5.2'
compile group: 'org.mapsforge', name: 'mapsforge-map-reader', version: '0.5.2'

compile group: 'org.slf4j', name: 'slf4j-android', version: '1.7.12'
compile group: 'org.slf4j', name: 'slf4j-api', version: '1.7.12'

}

Answer 1

发生这种情况是因为com.graphhopper:graphhopper:0.6-SNAPSHOT不在中央maven(或jcenter)中。

您可以查看所有版本here .

最后一个稳定版本是0.5.0

如果您想使用快照版本，您必须在build.gradle中添加存储库

repositories {
    jcenter() 
    maven { url "https://oss.sonatype.org/content/repositories/snapshots" }
}

这里是snapshot versions.
