AS升级到gradle 7.0时遇到的若干问题

阿里云仓库编译无法通过的问题

我们使用阿里镜像去下载库，升级到7.0时会出现以下错误：

opt-in, is unsupported. Switch Maven repository 
'maven(http://maven.aliyun.com/nexus/content/groups/public/)' to redirect to a secure 
protocol (like HTTPS) or allow insecure protocols.

解决办法：在项目的build.gradle中加入allowInsecureProtocol = true，如下：

No signature of method

报错信息：

No signature of method: build_6yelzgvzgvo56ckx44as1sptq.android() is applicable for argument types: (build_6yelzgvzgvo56ckx44as1sptq$_run_closure2) values: [build_6yelzgvzgvo56ckx44as1sptq$_run_closure2@1af01979]

在module的build.gradle中删除以下代码即可：

javaCompileOptions {
            annotationProcessorOptions {
                arguments = [fragmentArgsLogWarnings: 'false']
                includeCompileClasspath true
            }
        }

Android Gradle plugin requires Java 11

这里是需要安装 jdk 11，在官网下载这个版本的jdk安装即可
报错信息：

A problem occurred evaluating project ':cachewebviewlib'.
> Failed to apply plugin 'com.android.internal.library'.
   > Android Gradle plugin requires Java 11 to run. You are currently using Java 1.8.
     You can try some of the following options:
       - changing the IDE settings.
       - changing the JAVA_HOME environment variable.
       - changing `org.gradle.java.home` in `gradle.properties`.

you anti-virus program might be impacting your build performance

AS每次打开的时候都会报出以下警告：

将上面出现的文件夹加入杀毒白名单即可。
我电脑上安装的是360，所以在360的白名单中加入之后，就没有再报了。

gralde加速构建方法

## Project-wide Gradle settings.

# Specifies the JVM arguments used for the daemon process.
# 编译时使用守护进程
org.gradle.daemon=true
# The setting is particularly useful for tweaking memory settings.
# Default value: -Xmx1024m -XX:MaxPermSize=256m
# JVM最大允许分配的堆内存，按需分配
org.gradle.jvmargs=-Xmx2048m -XX:MaxPermSize=512m -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8
# When configured, Gradle will run in incubating parallel mode.
# This option should only be used with decoupled projects. More details, visit

gradle编译错误问题

在Terminal中输入graldew assembleRelease后，会报如下错误：

* What went wrong:

关键报错信息：AAPT: error: resource android:attr/ttcIndex not found.

出现这个问题的原因是，在一个项目中有module的 compileSdkVersion版本在28以下，将所有的module改为28及以上版本即可

Execution failed for task

在执行Build→Rebuild Project的时候，会在build控制台出现以下报错信息

出现这种问题，点击Run with --info可以看到报错的详细信息，根据提示去修改。
我这里具体是集成buggly有问题，我将buglly更新、热更新全部删掉，重新集成后不会报错了。弄好了之后回头来看问题应该是下面截图位置的错误，将bugly的插件相关信息删除即可。

jitpack发布出现的问题

Failed to apply plugin ‘com.github.dcendents.android-maven’.

git上的仓库release之后在jitpack.io上发布的时候会报一下错误：

FAILURE: Build failed with an exception.

* Where:
Script '/script/maven-plugin.gradle' line: 2

* What went wrong:
A problem occurred evaluating script.
> Failed to apply plugin 'com.github.dcendents.android-maven'.
   > Could not create plugin of type 'AndroidMavenPlugin'.
      > Could not generate a decorated class for type AndroidMavenPlugin.
         > org/gradle/api/publication/maven/internal/MavenPomMetaInfoProvider

解决办法，在对应的module的gradle.build文件里面增加以下配置

plugins {
    ...
    id 'maven-publish'
}

afterEvaluate {
    publishing {
        publications {
            release(MavenPublication) {
                from components.release
                groupId = 'com.petterp'
                artifactId = 'statex'
                version = '1.0-dev02'
            }
        }
    }
}

• groupId 是你的包名除 labrary 之前的全称
• artifactId 对应 labrary id ,即组件ID
• version 版本号

然后在提交上去，重新发布即可。
部分项目还有可能碰到Java 11的问题，报错如下，请参阅资料里面有解决方法。

Android Gradle plugin requires Java 11 to run. You are currently using Java 1.8.
