Android released to the pit encountered by jcenter (with new problems after upgrading gradle4.1)

The publication process reference article http://blog.csdn.net/super_spy/article/details/77994278;

Here are the problems I encountered during the publishing process;

1. Unmappable characters that encode GBK

For the javaDoc encoding problem, I use the method of skipping the generation of javaDoc to avoid errors, which is not perfect, but does not affect the release;

Add the following code to the project's build.gradle:

tasks.getByPath(": Library Model name to upload: mavenAndroidJavadocs").enabled = false

The above method is only suitable for versions before gradle 4.1. After upgrading gradle 4.1 recently, it will report Task with path ': Library Model name to upload : mavenAndroidJavadocs' not found in root project 'Project'.

You need to modify this line of code to:

tasks.getByPath(": Library Model name to upload: releaseAndroidJavadocs").enabled = false

2、 HTTP/1.1 404 Not Found [message:Repo 'maven' was not found]

Reference articlehttp://blog.csdn.net/tmac2000/article/details/53261141

The main reason is that the account type of bintray was created incorrectly. The registration page has two entries, one is a free trial version and the other is an open source version. Because the style of the free trial version is more eye-catching, it was registered as a free trial version inadvertently; so Just re-register an open source version;

3. The problem of 'org.gradle.api.internal.component.Usage' reported by gradle4.1

The version of bintray-release that needs to be modified is:

dependencies {
        classpath 'com.android.tools.build:gradle:3.0.0'
        classpath 'com.novoda:bintray-release:0.5.0'
}

4. The problem of "could not find com.android.tools.build:gradle:3.0.0." is reported when executing the gradle command in Terminal under gradle4.1

You need to add the library google() under repositories under buildscript as follows:

buildscript {
    repositories {
        jcenter()
        google()//添加该库
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.0'
        classpath 'com.novoda:bintray-release:0.5.0'
    }
}

5. Gradle 4.1 reports the problem of "unmappable characters encoding GBK":

The following code needs to be added to the project's build.gradle:

tasks.getByPath(": Library Model name to upload: releaseAndroidJavadocs").enabled = false
