kapt 发生异常：java.lang.OutOfMemoryError: GC 开销限制超出

Question

我正面临这个问题，在构建我的代码时，我遇到了这个异常。我已经尝试在 build.gradle 和 Manifest 文件中增加堆空间，但它们似乎都没有工作。我还更改了 gradle 属性，但效果不佳。

我认为我认为的问题是我正在使用数据绑定和空间，并且在为相同的文件生成文件时以某种方式出现了这个异常。

以下 gradle 设置对我有用。

-Xms256m -Xmx4096m -XX:MaxPermSize=350m -XX:ReservedCodeCacheSize=225m -XX:+UseCompressedOops

这将作为 org.gradle.jvargs 参数的值出现在您的 settings.gradle 文件中，例如

org.gradle.jvmargs=-Xms2560m -Xmx4096m -XX:MaxPermSize=350m -XX:ReservedCodeCacheSize=225m -XX:+UseCompressedOops

放线

org.gradle.jvmargs=-Xms2560m -Xmx4096m -XX:MaxPermSize=350m -XX:ReservedCodeCacheSize=225m -XX:+UseCompressedOops

到你的gradle.properties （项目属性）
