Android release apk keystore相關參數從環境變數或local.properties傳入build.gradle

build.gradle

方法如下:

android {
    signingConfigs {
        release {
            Properties properties = new Properties()
            def customKeystoreFilePath = System.getenv("KEYSTORE_FILEPATH")
            if (customKeystoreFilePath == null) {
                if (project.rootProject.file('local.properties').exists()) {
                    properties.load(project.rootProject.file('local.properties').newDataInputStream())
                    customKeystoreFilePath = properties.getProperty('customKeystoreFilePath')
                }
            }
            def customKeystorePassword = System.getenv("KEYSTORE_PASSWORD")
            if (customKeystorePassword == null) {
                if (project.rootProject.file('local.properties').exists()) {
                    properties.load(project.rootProject.file('local.properties').newDataInputStream())
                    customKeystorePassword = properties.getProperty('customKeystorePassword')
                }
            }
            def customKeyAlias = System.getenv("KEY_ALIAS")
            if (customKeyAlias == null) {
                if (project.rootProject.file('local.properties').exists()) {
                    properties.load(project.rootProject.file('local.properties').newDataInputStream())
                    customKeyAlias = properties.getProperty('customKeyAlias')
                }
            }
            def customKeyPassword = System.getenv("KEY_PASSWORD")
            if (customKeyPassword == null) {
                if (project.rootProject.file('local.properties').exists()) {
                    properties.load(project.rootProject.file('local.properties').newDataInputStream())
                    customKeyPassword = properties.getProperty('customKeyPassword')
                }
            }
            storeFile file(String.valueOf(customKeystoreFilePath))
            storePassword customKeystorePassword
            keyAlias customKeyAlias
            keyPassword customKeyPassword
        }
    }

....

buildTypes {
    release {
        minifyEnabled true
        shrinkResources true
        proguardFiles 'proguard.cfg'
        signingConfig signingConfigs.release
    }
}

build.gradle部分完成。

接著看需求:
1.從外面傳入以下四個參數

KEYSTORE_FILEPATH

KEYSTORE_PASSWORD

KEY_ALIAS

KEY_PASSWORD

2. 或定義在local.properties

customKeystoreFilePath=C\:\\your key store path\\your.keystore
customKeystorePassword=yourpassword
customKeyAlias=youralias
customKeyPassword=yourpassword

PS:

若password key 錯會噴如下錯誤:

Caused by: java.io.IOException: Keystore was tampered with, or password was incorrect

at com.android.ide.common.signing.KeystoreHelper.getCertificateInfo(KeystoreHelper.java:186)

Caused by: java.security.UnrecoverableKeyException: Password verification failed
