我已将我的 flutter rproject 迁移到 2.x 及其所有依赖项。一切正常，但是一旦我将其推送到 github action 作业就会失败并出现此错误：
$destinationPath = public_path("/images/".$image_name);
if (File::exists($destinationPath))
{
$contents = File::get($destinationPath);
Storage::disk('s3')->put($image_name,$contents,['mimetype' => 'image/svg+xml'],'public');
}
如果我尝试点击那个网址，我会得到 * What went wrong:
Execution failed for task ':libphonenumber:javaPreCompileRelease'.
