我有一个 ionic 项目。它已成功构建并在我的 android 手机中运行。突然有一天,当我运行命令“ionic cordova run android”时,我得到如下构建错误:

Dex: Error converting bytecode to dex:
Cause: Dex cannot parse version 52 byte code.
This is caused by library dependencies that have been compiled using Java 8 or above.
If you are using the 'java' gradle plugin in a library submodule add
targetCompatibility = '1.7'
sourceCompatibility = '1.7'
to that submodule's build.gradle file.

我试过“cordova clean”,但它不起作用。

你能帮我解决这个问题吗?

最佳答案

Version 52 字节码对应Java 8,你需要在你的app/build.gradle中添加以下内容,让你的项目兼容Java 8。

android {
...
defaultConfig {
jackOptions {
enabled true
}
}

compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
...
}
