在参考郭霖大神的文章 再见JCenter，将你的开源库发布到MavenCentral上吧 发布项目到Maven时候出现一点问题,在此记录下:

发布步骤按照上文进行就可以了,在点击pulish发布时时候出现几点问题:

1.No compatible plugin found in project for publishing

提示发布时没有找到兼容的插件

出现这个问题时,解决方法可能有以下几种:

1. 需要将项目根目录下build.gradle中apply plugin: "com.vanniktech.maven.publish"这一行移动到app下的build.gradle
2. 需要将app模块下的build.gradle中的apply plugin: 'com.android.application 修改为 apply plugin: 'com.android.library'
3. 删除app模块下defaultConfig'的applicationId

2.点击publish时提示找不到匹配的GROUP,提示404

• 需要将gradle.properties中GROUP=xxx修改成与sonatype上的Group ID一致,要注意大小写有区分,
  在https://s01.oss.sonatype.org的Staging Profiles中Name这一列也可以看到对应的GROUP名称

在此贴出项目中的完整代码:

项目根目录的build.gradle

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
    ext.kotlin_version = "1.5.20"
    repositories {
        google()
        mavenCentral()
    }
    dependencies {
        classpath "com.android.tools.build:gradle:4.0.2"
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath 'com.vanniktech:gradle-maven-publish-plugin:0.17.0'
    }
}

allprojects {
    repositories {
        google()
        mavenCentral()
    }
    plugins.withId("com.vanniktech.maven.publish") {
        mavenPublish {
            sonatypeHost = "S01"
        }
    }
}

app目录下的build.gradle

apply plugin: 'com.android.library'
apply plugin: 'kotlin-android'

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
        kotlinOptions {

        }
    }

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