我尝试在Android Studio上的Graphhopper演示项目上工作,我在这里找到:https://github.com/graphhopper/graphhopper/tree/master/android
在Gradle构建之后,我得到了这个错误:
错误:无法解决: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'
}
最佳答案
发生这种情况是因为com.graphhopper:graphhopper:0.6-SNAPSHOT
不在中央Maven(或jcenter)中。
您可以检查所有版本here。
最后一个稳定版本是0.5.0
如果要使用snapshot versions
,则必须在build.gradle
中添加存储库
repositories {
jcenter()
maven { url "https://oss.sonatype.org/content/repositories/snapshots" }
}
在这里snapshot versions.
