注意。我可以找到许多标题相似的问题，但是它们都没有在相同的上下文中，而且它们提出的解决方案都对我没有用。
我正尝试按照官方教程开始使用Flutter。 （https://flutter.io/get-started/test-drive/#terminal）
当我尝试跑步时
flutter run
该过程挂在“解决依赖项”上
bruno@bruno-Latitude-E5430-non-vPro ~/Projects/myapp $ flutter run
Using hardware rendering with device Android SDK built for x86. If you get graphics artifacts, consider enabling software rendering with "--enable-software-rendering".

所以，我尝试使用'-v'
flutter run -v
该进程挂在'[] [android /] / home / bruno / Projects / myapp / android / gradlew app：properties'

并收到此错误：
bruno@bruno-Latitude-E5430-non-vPro ~/Projects/myapp $ android/gradlew app:properties
FAILURE: Build failed with an exception.

运行flutter doctor。
如果一切正常，那么您的环境似乎有一个神秘的问题。
我将从检查您的PATH，导出等开始。
答案 1 :(得分：1)
从gradlew docs：“执行任何Gradle构建的推荐方法是在Gradle Wrapper（简称为“ Wrapper”）的帮助下进行。Wrapper是一个调用已声明版本的脚本，如有必要，请事先下载。”
所以，我的猜测是该过程没有停止，只是需要很长时间才能完成。我会检查网络活动以查看是否正在下载某些内容。
PS：手动运行gradlew命令时遇到的错误不是问题，如果进入android目录，它应该可以工作。
答案 2 :(得分：0)
我遇到了这个问题。事实证明，我在Android Studio项目的key.properties文件夹中找不到android/。
我得到的确切错误是：
* Error running Gradle:
ProcessException: Process "/Users/fakeuser/git/fakereponame/android/gradlew" exited abnormally:
Command: /Users/fakeuser/git/fakereponame/android/gradlew app:properties
Finished with error: Please review your Gradle project setup in the android/ folder.
出现此错误是因为我的android/app/build.gradle具有这段代码，这是从flutter教程中提取的。它对key.properties进行文件检查，但没有给出非常描述性的错误：
def keystoreProperties = new Properties()
def keystorePropertiesFile = rootProject.file('key.properties')
if (keystorePropertiesFile.exists()) {
keystoreProperties.load(new FileInputStream(keystorePropertiesFile))
}
