kapt An exception occurred: java.lang.OutOfMemoryError: GC overhead limit exceeded

Question

我遇到了这个问题，在构建我的代码时出现了这个异常。我尝试在 build.gradle 和 Manifest 文件中增加堆 space，但其中 none 似乎有效。我还更改了 gradle 属性，但效果不佳。

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不知何故出现了这个异常。

Answer 1

以下 gradle 设置对我有用。

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

这会作为 org.gradle.jvargs 参数的值进入您的 settings.gradle 文件，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。这可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"
