我的Flutter应用无法构建调试版本。我使用签名密钥构建了发行版，但是现在尝试构建调试它正在寻找storeFile（不存在，因为我将代码带到了没有密钥的另一台机器上）。我正在跑步：

   flutter build apk --debug

但是失败了

  

运行Gradle时出错：ProcessException：进程   ... \ android \ gradlew.bat“异常退出：

     

失败：构建失败，并出现异常。

     

位置：构建文件... \ android \ app \ build.gradle'行：54

     

出了什么问题：评估项目'：app'时发生问题。路径   不能为null或空字符串。 path ='null'

第54行是用于签名配置的版本

   storeFile file(keystoreProperties['storeFile'])

-调试不应该忽略它吗？为什么这是调试版本，为什么要尝试获取该文件？

这里是带发行版的build.gradle文件，已注释掉，因此我可以不带密钥库进行调试：

def localPropertiesFile = rootProject.file('local.properties')
if (localPropertiesFile.exists()) {
    localPropertiesFile.withReader('UTF-8') { reader ->
        localProperties.load(reader)
    }
}

def flutterRoot = localProperties.getProperty('flutter.sdk')
if (flutterRoot == null) {
    throw new GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")
}

def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
if (flutterVersionCode == null) {
    flutterVersionCode = '1'
}

def flutterVersionName = localProperties.getProperty('flutter.versionName')
if (flutterVersionName == null) {
    flutterVersionName = '1.6'
}

apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"

   def keystoreProperties = new Properties()
   def keystorePropertiesFile = rootProject.file('key.properties')
   if (keystorePropertiesFile.exists()) {
       keystoreProperties.load(new FileInputStream(keystorePropertiesFile))
   }
