无法编译我的Android项目

Question

我正在尝试编译我的Android版本，但出于某种原因，它说有一个错误，显然是我的Java。

To run dex in process, the Gradle daemon needs a larger heap.
It currently has approximately 910 MB.
For faster builds, increase the maximum heap size for the Gradle daemon to more than 2048 MB.
To do this set org.gradle.jvmargs=-Xmx2048M in the project gradle.properties.
For more information see https://docs.gradle.org/current/userguide/build_environment.html

使用我的Ubuntu它可以很好地工作，但是使用OSX它不会。

我的Ubuntu 16.04的Java版本是1.7.0_80-b15，我的OSX有1.7.0_79。

有人知道我该怎么做才能解决这个问题？

Answer 1

从昨天起就有同样的问题。

您需要从here安装JDK 1.8。我安装了8u92套件。

之后您需要更新JAVA_HOME环境变量。为了仅在Visual Studio中为Cordova项目更新它，您可以在屏幕截图中的Visual Studio选项中执行此操作。

然后一切都很好。

玩得开心！ ：）

我遇到了同样的问题，我发现我安装了Java SDK而不是JRE。重新安装SDK并选择安装安装程序附带的JRE解决了它。
