[安卓]错误：请在 gradle.properties 文件中定义"VERSION_NAME"

Question

最近，我开始学习android开发。我想开发一个具有音频/视频流转换功能的应用程序。所以我尝试导入VLC模块来接收流数据。

当我导入VLC模块时，控制台显示错误。

//the errors console shows
ERROR: Please define "VERSION_NAME" in your gradle.properties file
**Open File**

我点击open file。渐变配置文件在IDE中打开。重点是显示'apply plugin: "com.vanniktech.maven.publish"'的第三行

//gradle configure file
apply plugin: 'com.android.library'
apply plugin: 'com.github.dcendents.android-maven'
apply plugin: "com.vanniktech.maven.publish"

那么，如何编辑渐变配置文件呢？

Answer 1

您需要在defaultConfig:中添加versionName和versionCode

defaultConfig {
versionCode rootProject.ext.versionCode
versionName rootProject.ext.versionName
...

这些可能与应用程序moudle的versionName和versionCode不同。

Answer 2

消息显示gradle.properties，但您打开的是build.gradle脚本。也许该文件还不存在？如果是这样，只需在build.gradle文件旁边创建(或打开(gradle.properties并添加所需的属性。
