kapt出现异常：java.lang.OutOfMemoryError：GC超时限制已超过

Question

我遇到了一个问题，编译代码时出现异常。我尝试在build.gradle和Manifest文件中增加堆空间大小，但似乎都没有起作用。我还更改了gradle属性，但也没有奏效。

我认为问题可能是由于我正在使用数据绑定和room，在生成相同的文件时会发生这个异常。

Answer 1

以下Gradle设置对我有效。

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

这应该放在你的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

插入行

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

添加到您的gradle.properties（项目属性）中

那么jvargs设置应该放在settings.gradle和grale.properties中吗？ - htafoya

另一种为特定作业设置堆大小的方法是为每个作业使用环境变量。这可以确保当需要更高内存的作业未被使用时，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"
