cordova buildでError: spawn EACCESが発生した時の対処方法

cordova buildでError: spawn EACCESと怒られた

$ cordova build android
ANDROID_HOME=/Users/bin/android-sdk/
JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_101.jdk/Contents/Home
Error: spawn EACCES

よくわからない。ググってもionicのことしか出てこないし書いてあるようにフォルダの権限を変えても直らないし。しばらくはまったけど、以下で直った。

対処方法

chmod +x "/Applications/Android Studio 3.0 Preview.app/Contents/gradle/gradle-4.0-milestone-1/bin/gradle”

どうやらAndroid Studioをアップデートしてgradeの実行権限が変わったためみたいだった。
ヒントは以下。gradeの実行の直後でエラーになってる。
