java - 问题可能是由于守护程序配置不正确引起的

问题描述

我在运行 Flutter Project 时遇到问题我尝试了多个版本的 gradle 并且所有相同的错误

FAILURE: Build failed with an exception.

* What went wrong:
Unable to start the daemon process.
This problem might be caused by incorrect configuration of the daemon.
For example, an unrecognized jvm option is used.
Please refer to the User Manual chapter on the daemon at https://docs.gradle.org/5.6.2/userguide/gradle_daemon.html

我试图将 gradle 更改为： gradle-5.6.2-all gradle-6.1.1-all

我试图添加org.gradle.jvmargs=-Xmx1024mgradle-wrapper.properties

我试图删除 .gradle 并重新构建它

我试图在构建时禁用 Windows Defender，但同样的问题

解决方案

恕我直言，您的机器无法为 gradle 进程提供它请求的堆空间。

Error occurred during initialization of VM
Could not reserve enough space for 1572864KB object heap

意味着运行 gradle 的 JVM 需要来自操作系统的 1.5GB 堆，但它没有得到。

你可以尝试什么：

在构建的根目录中修改或创建gradle.properties文件。

放

org.gradle.jvmargs=-Xmx1024M

所以你的 gradle 进程只消耗 1GB 的内存。

./gradlew --stop在运行下一个构建之前运行以停止所有守护进程。

但是：请确保您的系统有足够的内存资源来运行您想要运行的所有应用程序/进程。

如果您的系统有足够的内存资源：在我看来，您可能正在使用 32 位 JVM。32 位 Java JVM 的内存限制非常低。请切换到 64 位 JVM 并确保您的 JAVA_HOME 环境变量指向 64 位 JVM。这将允许您分配更多的内存。
