不能通过visual studio cordova构建签名的Android包 [英] Cannot build signed android package through visual studio cordova

问题描述

我试图使用Visual Studio 2015 Cordova工具为我的Android应用程序构建签名的发行包。
我使用Cordova 5.1.1，这需要我提供一个build.json文件的构建过程，告诉应用程序在哪里的密钥库和什么密码正在使用。
然而，当我添加build.json文件时，我无法成功构建发布。

我遵循本指南：

选择前三个字节作为截图，并删除它们，然后保存文件。解析器现在应该接受该文件，签名将按预期工作。

I am trying to build a signed release package for my Android application using Visual Studio 2015 Cordova Tools. I am using Cordova 5.1.1, which requires that I supply the build process with a build.json file, telling the application where the keystore are and what password is using. However when I add the build.json file, I am not able to make a successful build to release.

I followed this guide: https://github.com/Microsoft/cordova-docs/tree/master/tutorial-package-publish#android

And got this error (with path edited out):

What am I doing wrong? It seems like it cant parse the JSON?

解决方案

This issue is caused because the default build.json has a BOM that the NodeJS JSON parser doesn't like. You can fix this in a number of ways, but the simplest is to open the file using Visual Studio's Binary editor.

Right-click build.json, select "Open With...", then choose the "Binary Editor" from the list. You should see something like this:

Select the first three bytes as in the screenshot, and delete them, then save the file. The parser should now accept the file, and signing will work as expected.
