Gradle，加载外部文件以签署配置

Question

我一直在努力为项目添加风味，但遇到了以下问题。我没有添加keystore 路径、别名和密码，而是将它们添加到.properties 文件中，并尝试在build.gradle 中访问它们。

所以我就是这样做的，

该项目在 git 中，因此如果我将其保存在 gradle.properties 中，其他用户也会获得我的本地路径到 .properties 文件路径。出于这个原因，我在local.properties 中添加了.properties 路径。在build.gradle 中，我从local.properties 读取变量并将每个变量写入属性文件。

local.properties

variable.prop=C\:\\Users\\user\\signing\\project\\pro.properties

build.gradle

buildscript {
    repositories {
        maven { url 'https://maven.fabric.io/public' }
    }

    dependencies {
        classpath 'io.fabric.tools:gradle:1.+'
    }
}

apply plugin: 'com.android.application'
apply plugin: 'io.fabric'
apply plugin: 'com.neenbedankt.android-apt'

repositories {
    maven { url 'https://maven.fabric.io/public' }
}

def versionMajor = 1
def versionMinor = 0
def versionPatch = 1
def versionBuild = 1

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.3"

   Properties props = new Properties()
   props.load(project.rootProject.file('local.properties').newDataInputStream())
   def localPropertiesPath = props.getProperty('variable.prop', null);
   if (localPropertiesPath == null)
        throw new GradleException("Unable to find properties file. Variable might not be added in local.properties or file may not exist in given path")
   else {
        def propFile = file(localPropertiesPath)
        if (propFile.canRead()) {
            Properties properties = new Properties()
            properties.load(new FileInputStream(propFile))

            signingConfigs {

                uat {
                    storeFile file(properties['uatKeystorePath'])
                    keyAlias properties['uatKeyAlias']
                    keyPassword properties['uatKeyPassword']
                    storePassword properties['uatStorePassword']
                }

                release {
                    storeFile file(properties['releaseKeystorePath'])
                    keyAlias properties['releaseKeyAlias']
                    keyPassword properties['releaseKeyPassword']
                    storePassword properties['releaseStorePassword']
                }
            }

            defaultConfig {
                applicationId "com.package.name"
                minSdkVersion 15
                targetSdkVersion 23
                versionCode versionMajor * 1000000 + versionMinor * 10000 + versionPatch * 100 + versionBuild
                versionName "${versionMajor}.${versionMinor}.${versionPatch}"
                setMultiDexEnabled true
            }

            dexOptions {
                javaMaxHeapSize "2048M"
            }

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

在这里，在properties.load(new FileInputStream(propFile)) 行中它总是抛出

Malformed \uxxxx encoding.

我试过了，

1. 硬编码pro.properties的路径，而不是从local.properties获取

2. 尝试如下link

3. 还尝试更改 forward-slash、backslash 和 escape-char 组合

但到目前为止没有任何帮助。任何帮助将不胜感激

在 pro.properties 文件中

uatKeystorePath=C:\Users\user\.signing\project\uat_keystore.jks
uatStorePassword=StorePassword
uatKeyAlias=AliasName
uatKeyPassword=KeyPassword
releaseKeystorePath=C:\Users\user\.signing\project\release_keystore.jks
releaseStorePassword=StorePassword
releaseKeyAlias=AliasName
releaseKeyPassword=KeyPassword

我无法发表评论，所以我必须回答，但我只想问您，您的真实文件中是否有与您的问题相同的错字？

variable.prop=C\:\\Users\\user\\signing\\project\\pro.properties

我的意思是C和:之间的反斜杠
