Question

这是我的构建文件。我使用的是Intellij CE。我试图使用this yahoo finance api：

group 'com.scrap'
version '1.0-SNAPSHOT'

apply plugin: 'java'

sourceCompatibility = 1.5

repositories {
    mavenCentral()
}

dependencies {
    compile group: 'com.yahoofinance-api', name: 'YahooFinanceAPI', version: '4.0.0'
    compile 'joda-time:joda-time:2.2'
    testCompile group: 'junit', name: 'junit', version: '4.11'
}

当我在Gradle工具窗口中手动同步项目时，我在yahoofinance库下面出现一条红线，并显示一条消息

unable to resolve com.yahoofinance-api:YahooFinanceAPI:4.0.0

我做错了什么？

Answer 1

4.0 Maven中不存在YahooFinanceAPI。最新的一个是3.5.0 - cf - https://mvnrepository.com/artifact/com.yahoofinance-api/YahooFinanceAPI

通过修改版本并添加用于创建胖罐的选项

进行测试

group 'com.scrap'
version '1.0-SNAPSHOT'

apply plugin: 'java'

sourceCompatibility = 1.5

repositories {
    mavenCentral()
}

dependencies {
    compile group: 'com.yahoofinance-api', name: 'YahooFinanceAPI', version: '3.5.0' //Changed version
    compile 'joda-time:joda-time:2.2'
    testCompile group: 'junit', name: 'junit', version: '4.11'
}

// Added new section
jar {
    from {
        (configurations.runtime).collect {
            it.isDirectory() ? it : zipTree(it)
        }
    }
    manifest {
        attributes("Main-Class": "Main" )
    }
}
