通过gradlew使用-Xmx和-Xms运行应用程序 [英] Run application via gradlew with -Xmx and -Xms

问题描述

我有一个申请.我通过

gradlew run-app

或调试

gradlew debug-app

有效.如何将"-Xmx"参数传递给我运行的应用程序(调试)? 是否可以在不编辑build.gradle文件的情况下这样做?

It works. How do I pass '-Xmx' argument into the application which I run (debug)? Is it possible to do so without edditing build.gradle file?

我发现了这个 为未知的命令行选项'-X'分级

尝试时会收到类似的错误

I get a similar error when I try

gradlew debug-app -Xmx2000m

错误

FAILURE: Build failed with an exception.

* What went wrong:
Problem configuring task :debug-app from command line.
> Unknown command-line option '-X'.

我试图在GRADLE_USER_HOME目录中创建文件gradle.properties(默认情况下为USER_HOME/.gradle).

---

I tried to create a file gradle.properties in GRADLE_USER_HOME directory (by default, it is USER_HOME/.gradle).

org.gradle.jvmargs=-XX\:MaxHeapSize\=4256m -Xmx4256m -Xms2000m

我也试图在项目文件夹gradle.properties中的org.gradle.jvmargs=-Xmx2000m.

I also tried to org.gradle.jvmargs=-Xmx2000m in project folder gradle.properties.

即使在我运行应用程序时，我也会看到Committed Memory大小为<. 520 MiB

And even then when I run an application, I see Commited Memory size is < 520 MiB

这是我作为普通Java应用程序运行时的情况

And this is when I run it as a normal Java App

在第二种情况下，当我使用-Xms，-Xmx作为普通Java应用程序运行该应用程序时，由于我传递了-Xmx4512m -Xms2512m参数，因此Committed Memory大小约为3.5 GiB.

In the second case, when I run the application as a normal Java app with -Xms, -Xmx, Commited Memory size is about 3.5 GiB because I passed -Xmx4512m -Xms2512m parameters.

推荐答案

将此添加到您的gradle.properties文件中:

Add this in your gradle.properties file :

org.gradle.jvmargs=-Xmx2000m

从此处

org.gradle.jvmargs

指定用于守护进程的jvmargs.设置是 在调整内存设置时特别有用.此刻 默认设置在内存方面非常慷慨.

Specifies the jvmargs used for the daemon process. The setting is particularly useful for tweaking memory settings. At the moment the default settings are pretty generous with regards to memory.

edit:我的回答是关于gradle守护进程jvm，而不是应用程序jvm.您必须使用 jvmArgs属性

edit : my answer what about the gradle daemon jvm, not the app jvm. You have to use the jvmArgs property

用于为进程启动JVM的额外参数.才不是 包括系统属性和最小/最大堆大小.

The extra arguments to use to launch the JVM for the process. Does not include system properties and the minimum/maximum heap size.
