Maven: Failed to execute goal on project test: Could not resolve dependencies for project

[Alceatraz]

我一直使用Maven管理项目，但是升级2.0-RC以后出现了一些问题：

为了防止是网络问题，我用了美国VPS

这是测试pom文件，会发生以下错误

我觉得这个问题应该是Maven的，因为使用gradle管理项目就没有问题，使用了同样的maven-central和jcenter-bintray

group = "com.example"
version = "0.0.0"
plugins {
    java
    kotlin("jvm") version "1.4.21"
}
java {
    sourceCompatibility = JavaVersion.VERSION_11
    targetCompatibility = JavaVersion.VERSION_11
}
repositories {
    mavenCentral()
    jcenter()
}
tasks {
    javadoc { options.encoding = "UTF-8" }
    compileJava { options.encoding = "UTF-8" }
    compileTestJava { options.encoding = "UTF-8" }
}
dependencies {
    val miraiVersion = "2.0-RC"
    runtimeOnly("net.mamoe:mirai-core:$miraiVersion")
    api("net.mamoe:mirai-core-api:$miraiVersion")
}

因为网络原因，我真的不想用Gradle，各位有没有什么办法？

确认一下，我觉得我可能误解了，只需要mirai-core-jvm而不是mirai-core和mirai-core-api是吗？

[Him188]

现在 mirai 模块架构是 mirai-core 和 mirai-core-api.

Kotlin 1.4 起改了一些 MPP 发布策略, Gradle 会自动解决目标平台问题, 而 Maven 不会. 因此 maven 需要额外添加 -jvm 后缀, 使用 mirai-core-jvm 和 mirai-core-api-jvm.

[Alceatraz]

明白了，原来那个就不是给java用的，加上-jvm以后问题全部解决了，thx

这有可能是没有安装 Kotlin 插件而无法解决依赖, 查看 https://github.com/mamoe/mirai/blob/dev/docs/ConfiguringProjects.md#3-%E6%B7%BB%E5%8A%A0-kotlin-%E4%BE%9D%E8%B5%96
