1.在项目根目录下的build.gradle文件中,
allprojects {
repositories {
maven {
url 'https://s01.oss.sonatype.org/content/repositories/releases/'
}
}
}
2.在entry模块的build.gradle文件中,
dependencies {
implementation('com.gitee.chinasoft_ohos:DBFlow_lib:1.0.0')
implementation('com.gitee.chinasoft_ohos:DBFlow_sqlcipher:1.0.0')
implementation('com.gitee.chinasoft_ohos:DBFlow_reactive-streams:1.0.0')
implementation('com.gitee.chinasoft_ohos:DBFlow_contentprovider:1.0.0')
implementation('com.gitee.chinasoft_ohos:DBFlow_paging:1.0.0')
implementation('com.gitee.chinasoft_ohos:DBFlow_livedata:1.0.0')
......
}
在sdk6,DevEco Studio 2.2 Beta2下项目可直接运行 如无法运行,删除项目.gradle,.idea,build,gradle,build.gradle文件, 并依据自己的版本创建新项目,将新项目的对应文件复制到根目录下
