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

Question

我在构建代码时遇到了这个问题，我遇到了这个异常。我尝试增加 build.gradle 和 Manifest 文件中的堆空间，但它们似乎都没有工作。我也更改了 gradle 属性，但效果不佳。

我认为问题在于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，它碰巧给出了这个异常。

Answer 1

以下 gradle 设置对我有用。

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

这在你的 settings.gradle 文件中作为 org.gradle.jvargs 参数的值，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

到您的 gradle.properties（项目属性）

Answer 2

为特定作业设置堆大小的另一种方法是为每个作业使用环境变量。这样可以确保在不使用需要更高内存的作业时内存可用。

GRADLE_OPTS="-Dorg.gradle.jvmargs=-Xms1024M -Xmx8192M -XX:PermSize=512M -XX:MaxPermSize=2048 -XX:+CMSClassUnloadingEnabled -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8"

JAVA_OPTS="-XX:MaxPermSize=2048M"
