Android gradle编译错误OOM:java heap space的解决办法

Android开发中,在编译较大规模项目时,出现内存溢出错误:

OutOfMemeryError OOM:java heap space;

尝试解决办法:

1. 开发项目根项目下增加/demo/gradle.properties配置文件

## For more details on how to configure your build environment visit
# http://www.gradle.org/docs/current/userguide/build_environment.html
#
# Specifies the JVM arguments used for the daemon process.
# The setting is particularly useful for tweaking memory settings.
# Default value: -Xmx1024m -XX:MaxPermSize=256m
# org.gradle.jvmargs=-Xmx2048m -XX:MaxPermSize=512m -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8
#
# When configured, Gradle will run in incubating parallel mode.
# This option should only be used with decoupled projects. More details, visit
# http://www.gradle.org/docs/current/userguide/multi_project_builds.html#sec:decoupled_projects
# org.gradle.parallel=true

org.gradle.jvmargs=-Xmx8192M -Dkotlin.daemon.jvm.options\="-Xmx8192M"

2. 项目目录/demo/gradle/wrapper/gradle-wrapper.properties

#Tue Jul 09 14:47:41 CST 2019
distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-5.5-all.zip
#Set jvmargs as 4096M avoid to OOM:java heap space
org.gradle.jvmargs=-Xmx8192M
# Enables R8 for Android Library modules only. (default true, you can disable)
android.enableR8.libraries = true
# Enables R8 for all modules.(default true, you can disable)
android.enableR8 = true

通过上面两个配置文件,编译项目还是出现OutOfMemeryError OOM:java heap space

猜测可能事配置没有写对,/demo/gradle.properties中应该配置:

org.gradle.jvmargs=-Xmx2048m -XX:MaxPermSize=512m -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8

最后找到了全局的 /home/hulk/.gradle/gradle.properties,做如下修改,其他代码库也能使用.

3. 修改系统gradle全局的 gradle.properties

/home/hulk/.gradle/gradle.properties  (无此文件就新建一个)

#开启并行编译，相当于多条线程再走
# org.gradle.parallel=true
#开启线程守护，第一次编译时开线程，之后就不会再开了
org.gradle.daemon=true
 
#Set jvmargs as 4096M avoid to OOM:java heap space
#配置编译时的虚拟机大小:具体数值根据本机内存大小进行设置如机器为16G内存,可设置为8G(8192M)
org.gradle.jvmargs=-Xmx8192m -XX:MaxPermSize=2048m -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8
#仅设置前面虚拟内存大小也行,如下
#org.gradle.jvmargs=-Xmx8192M   
 
#启用新的孵化模式
org.gradle.configureondemand=true
 
#代理服务器
systemProp.http.proxyHost=proxy.lfk.xxx-inc.cn
systemProp.http.proxyPort=3128
systemProp.https.proxyHost=proxy.lfk.xxx-inc.cn
systemProp.https.proxyPort=3128

通过以上的全局配置修改调整: 把虚拟内存设置为8G: org.gradle.jvmargs=-Xmx8192M

再编译,就没有问题了,记录一下,希望码友们用得着
