Android BuildConfig 字段生成字符串不正确

Question

开始新项目的最后一天，我在构建配置中创建了一些变量，作为在发布和调试构建之间单独处理它们的好习惯，如下所示:

...
buildTypes {
    release {
        minifyEnabled false
        buildConfigField("String", "PARSE_APP_ID", "xxxxxxxxxxxxxxxxxxxxxxxxxxx")
        buildConfigField("String", "PARSE_CLIENT_ID", "xxxxxxxxxxxxxxxxxxxxxxxxxx")
        buildConfigField("String", "FACEBOOK_APP_ID", "999999999999999")
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
    debug{
        minifyEnabled false
        buildConfigField("String", "PARSE_APP_ID", "xxxxxxxxxxxxxxxxxxxxxxxxxxx")
        buildConfigField("String", "PARSE_CLIENT_ID", "xxxxxxxxxxxxxxxxxxxxxxxxxx")
        buildConfigField("String", "FACEBOOK_APP_ID", "999999999999999")
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
...

问题是它没有正确地创建字符串，而是直接打印字符串而没有这样的引号:

public final class BuildConfig {
  .....
  // Fields from build type: debug
  public static final String FACEBOOK_APP_ID = 99999999999999999;
  public static final String PARSE_APP_ID = xxxxxxxxxxxxxxxxxxxxxxxx;
  public static final String PARSE_CLIENT_ID = xxxxxxxxxxxxxxxxxxxxxxxxx;
}

显然这会给你带来编译错误，我试图在 stackoverflow 中找到如何解决这个问题，因为这会导致我的构建出现错误，但没有找到任何相关信息。如何让 gradle 正确打印带引号的字符串？

写完这篇文章后，我找到了方法，似乎值的打印方式与它们定义的方式相同，因此如果您向其中添加转义引号，它将起作用，例如:

buildTypes {
        release {
            minifyEnabled false
            buildConfigField("String", "PARSE_APP_ID", '"xxxxxxxxxxxxxxxxxxxxxxxx"')
            buildConfigField("String", "PARSE_CLIENT_ID", '"xxxxxxxxxxxxxxxxxxxxxxxxx"')
            buildConfigField("String", "FACEBOOK_APP_ID", '"999999999999999"')
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }

之后，重建，它将正确打印字符串值:

public final class BuildConfig {
  ....
  // Fields from build type: debug
  public static final String FACEBOOK_APP_ID = "999999999999999999";
  public static final String PARSE_APP_ID = "xxxxxxxxxxxxxxxxxxxxxxxxxxx";
  public static final String PARSE_CLIENT_ID = "xxxxxxxxxxxxxxxxxxxxxxxx";
}
