如何在gradle中调整jvm参数以适应dex内存？ [英] How do you adjust jvm args for dex memory in gradle?

问题描述

 ：app：dexXXXXX异常处理在线程pool-1-thread-4java.lang.OutOfMemoryError：Java堆空间
  

I希望像我们以前对Maven插件所做的那样，在gradle中提升jvm min / max设置：

 < groupId> ; com.jayway.maven.plugins.android.generation2< /&的groupId GT; 
< artifactId> android-maven-plugin< / artifactId> 
< version> 3.6.0< / version> 
< extensions> true< / extensions> 
<配置> 
< sdk> 
<平台> $ {android.platform}< /平台> 
< / sdk> 
< undeployBeforeDeploy> true< / undeployBeforeDeploy> 
< dex> 
< jvmArguments> 
< jvmArgument> -Xms1024m< / jvmArgument> 
< jvmArgument> -Xmx2048m< / jvmArgument> 
< / jvmArguments> 
< / dex> 
  

但是在gradle中的android插件文档中，我只能看到这些选项：

  android {
 dexOptions {
 incremental false 
 preDexLibraries = false 
 jumboMode = false 
} 
} 
  

有没有办法做到这一点？有一个gradle.properties文件，但似乎只有jvmargs for gradle本身。

解决方案

有一个未记录的dexOptions标志。

dexOptions {
javaMaxHeapSize2g
}

我从谷歌组帖子中找到该标志。

I have an Android project which is currently running out of heap space during the dex step:

 :app:dexXXXXX Exception in thread "pool-1-thread-4"  java.lang.OutOfMemoryError: Java heap space

I would like to bump up the jvm min/max settings in gradle like we used to do with the Maven plugin:

      <groupId>com.jayway.maven.plugins.android.generation2</groupId>
      <artifactId>android-maven-plugin</artifactId>
      <version>3.6.0</version>
      <extensions>true</extensions>
      <configuration>
        <sdk>
          <platform>${android.platform}</platform>
        </sdk>
        <undeployBeforeDeploy>true</undeployBeforeDeploy>
        <dex>
          <jvmArguments>
              <jvmArgument>-Xms1024m</jvmArgument>
              <jvmArgument>-Xmx2048m</jvmArgument>
          </jvmArguments>
        </dex>

But in the docs for the android plugin in gradle I only see these options:

   android {
    dexOptions {
        incremental false
        preDexLibraries = false
        jumboMode = false
    }
   }

Is there a way to do it? There is a gradle.properties file but that just seems to have jvmargs for gradle itself.

解决方案

There is an undocumented dexOptions flag.

dexOptions { javaMaxHeapSize "2g" }

I found the flag from a google groups post. https://groups.google.com/forum/#!topic/adt-dev/P_TLBTyFWVY
