建筑项目:OutOfMemory(Android studio 3.4)



我已经将Android Studio 3.x升级到3.4(使用Grade插件(,现在,我的项目的构建非常非常长,并且有一个最终错误(在构建4-5分钟后(:

> Task :app:compileDevelopmentDebugJavaWithJavac
Gradle may disable incremental compilation as the following annotation processors are not incremental: butterknife-compiler-10.1.0.jar (com.jakewharton:butterknife-compiler:10.1.0), esperandro-2.6.0.jar (de.devland.esperandro:esperandro:2.6.0).
Consider setting the experimental feature flag android.enableSeparateAnnotationProcessing=true in the gradle.properties file to run annotation processing in a separate task and make compilation incremental.
Note: [1] Wrote GeneratedAppGlideModule with: [com.bumptech.glide.integration.okhttp3.OkHttpLibraryGlideModule]
warning: No SupportedSourceVersion annotation found on de.devland.esperandro.processor.EsperandroAnnotationProcessor, returning RELEASE_6.
warning: Supported source version 'RELEASE_6' from annotation processor 'org.gradle.api.internal.tasks.compile.processing.TimeTrackingProcessor' less than -source '1.8'

The system is out of resources.
Consult the following stack trace for details.

在此升级(今天早上完成(之前,一切正常。请问你有一些调查方法吗?

build.gradle:

buildscript {
    repositories {
        google()
        jcenter()
    }
    dependencies {
        // https://developer.android.com/studio/releases/gradle-plugin.html
        classpath 'com.android.tools.build:gradle:3.4.0'
        // https://developers.google.com/android/guides/google-services-plugin
        classpath 'com.google.gms:google-services:4.2.0'
        classpath 'com.google.firebase:firebase-plugins:1.2.0'
        // https://github.com/JakeWharton/butterknife
        classpath 'com.jakewharton:butterknife-gradle-plugin:10.1.0'
    }
}

gradle-wrappers.properties:

distributionUrl=https://services.gradle.org/distributions/gradle-5.1.1-all.zip

增加 Gradle 构建系统可用的内存。

将其放入您的gradle.properties文件中:

org.gradle.jvmargs=-Xmx2g

mx表示最大内存,2g表示两千兆字节。

如果已经有org.gradle.jvmargs请在末尾添加-Xmx2g。如果有旧-Xmx,请将其移除。

应用所需的 GB 不应超过 3 GB。 添加更多 GB 并不一定能提供更好的性能。

如果您还使用 options.fork,请尝试 options.forkOptions.setMemoryMaximumSize("2g"(

对我来说,org.gradle.jvmargsjavaMaxHeapSize不起作用。所以我注释掉了很多gradle脚本命令来诊断导致问题的原因,并找到了options.fork

删除options.fork也可以。
