gradle錯誤 解決辦法 （彙總 不按期更新）

1. Could not find com.android.tools.build:aapt2:3.3.2-5309881

build失敗，報錯

解決辦法：在項目下的build.gradle repositories下加入 google()

buildscript {
    repositories {
        jcenter()
        google()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.3.2'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
        google()
    }
}

解決辦法：更換項目下repositories的順序，如

repositories {
    mavenCentral()
    maven {
        url 'https://jitpack.io'
    }
    maven { url "https://dl.bintray.com/thelasterstar/maven/" }

    google()
    jcenter()
}
複製代碼

4. com.android.ide.common.signing.KeytoolException: Failed to read key ??????

.properties用來存放app名稱或者keystore信息時，出現中文會讀取亂碼。

解決辦法：首先項目的文件編碼都改成utf-8

而後取值的時候，如取keystore alias使用new String(KEYSTORE_ALIAS.getBytes("iso8859-1"), "UTF-8")
