使用 Maven 和 IntelliJ IDEA 处理大型项目的技巧 [英] Tips for Handling large projects with Maven and IntelliJ IDEA

问题描述

我正在阅读 这篇 博客文章介绍了团队使用 Intellij Idea 进行大型 maven 项目的经验，还查看了 类似 大约 2 年前针对 IDEA v.10.0.2 发布的问题.

I was reading this blog post about the experience of a team using Intellij Idea for large maven projects and have also looked at a similar question posted around 2 years back for IDEA v.10.0.2.

前面提到的一个技巧很有意义:
将 C:Users$user.IntelliJIdea12 移动到防病毒软件无法访问扫描的文件夹中.

One of the tips mentioned in the former made a whole lot of sense :
Move C:Users$user.IntelliJIdea12 into a folder not access-scanned by the antivirus.

我搜索了以性能为中心的 VM 选项，目前我的 idea64.exe.vmoptions 看起来像这样:

I have searched around for performance centric VM options and currently my idea64.exe.vmoptions looks like this :

-Xms1200m
-Xmx1200m
-XX:MaxPermSize=200m
-ea
-server
-XX:+DoEscapeAnalysis
-XX:+UseCompressedOops
-XX:+UnlockExperimentalVMOptions
-XX:+UseParallelGC
-XX:ReservedCodeCacheSize=64m
-XX:+UseCodeCacheFlushing
-Dsun.io.useCanonCaches=false

问题

1. 您还有其他类似的技巧来提高大型/大型 maven 项目的 Intellij IDEA(12.1.3、64 位)性能吗?

1. Do you have any more such tips to improve Intellij IDEA (12.1.3, 64 bit) performance with large/huge maven projects ?

您能否分享您在 idea64.exe.vmoptions 和/或 IDEA 配置中的 idea.properties 中的虚拟机选项的发现.

Could you please share discoveries you have made w.r.t VM options in idea64.exe.vmoptions and/or IDEA configuration in idea.properties.

我曾尝试使用 JDK 7 来启动 IDEA，但这似乎并没有以一种或另一种方式严重影响它的性能.如果您尝试过这样做，您是否也有同样的经历?

I have tried using JDK 7 to startup IDEA but this does not seem to terribly affect it's performance one way or the other. If you have tried doing so, did you experience the same ?

推荐答案

按照@CrazyCoder 的建议，我按照官方FAQ 中关于此事的步骤:

As suggested by @CrazyCoder, I followed the steps on the official FAQ regarding this matter:

IntellJ IDEA 性能问题的常见解决方案

具体来说，以下内容似乎产生了明显的影响:

Specifically, the following seemed to have had an appreciable affect:

1. 将 c:/Users/$user/.IntelliJIdea12 移动到 McAfee 的按访问扫描仪排除的位置，并更新了 $INTELLJ_INSTALL_FOLDER/bin/idea.properties 像这样指向新位置(其中 c:/dev 是 McAfee 排除的文件夹):

1. Moved the c:/Users/$user/.IntelliJIdea12 to a location excluded by McAfee's on-access-scanner, and updated $INTELLJ_INSTALL_FOLDER/bin/idea.properties to point to the new location like so (where c:/dev is the folder excluded by McAfee):

idea.config.path=c:/dev/.IntelliJIdea12/config
idea.system.path=c:/dev/.IntelliJIdea12/system
idea.plugins.path=c:/dev/.IntelliJIdea12/config/plugins
idea.log.path=c:/dev/.IntelliJIdea12/system/log

idea.config.path=c:/dev/.IntelliJIdea12/config
idea.system.path=c:/dev/.IntelliJIdea12/system
idea.plugins.path=c:/dev/.IntelliJIdea12/config/plugins
idea.log.path=c:/dev/.IntelliJIdea12/system/log

在 $INTELLJ_INSTALL_FOLDER/bin/idea.properties 中设置 idea.jars.nocopy=true，如 这篇博文.

In $INTELLJ_INSTALL_FOLDER/bin/idea.properties set idea.jars.nocopy=true as documented in this blog post.

恢复为库存$INTELLIJ_INSTALL_FOLDER/bin/idea64.exe.vmoptions.剩下的唯一更改是 Too low heap size for a 64-位JVM.这是我目前在该文件中的内容:

Reverted back to the stock $INTELLIJ_INSTALL_FOLDER/bin/idea64.exe.vmoptions. The only changes that remains are those suggested in Too low heap size for a 64-bit JVM. Here is what I have in the that file currently:

-Xms1200m
-Xmx1200m
-XX:+UseCompressedOops
-XX:MaxPermSize=350m
-XX:ReservedCodeCacheSize=96m
-XX:+UseCodeCacheFlushing
-ea
-Dsun.io.useCanonCaches=false
-Djava.net.preferIPv4Stack=true

-Xms1200m
-Xmx1200m
-XX:+UseCompressedOops
-XX:MaxPermSize=350m
-XX:ReservedCodeCacheSize=96m
-XX:+UseCodeCacheFlushing
-ea
-Dsun.io.useCanonCaches=false
-Djava.net.preferIPv4Stack=true

禁用 Git 集成插件，因为我主要使用命令行 Cygwin-Git.

Disabled Git integration plugin since I mostly use command line Cygwin-Git.

监控 .IntelliJIdea12/idea.log 很有用.例如:我在尝试打开项目中的 zip 文件时发现它经常记录错误后，我禁用了 osmorc(用于 OSGI)插件.示例错误:

It was useful to monitor .IntelliJIdea12/idea.log. For example : I disabled the osmorc (for OSGI) plugin after seeing that it was frequently logging error while trying to opening zip files in the projects. Sample error :

警告 - pi.vfs.impl.jar.JarHandlerBase - 打开 zip 文件时出错:C:deva-maven-projectpom.xml java.util.zip.ZipException: 错误打开 zip 文件在 java.util.zip.ZipFile.open(本机方法)
在 java.util.zip.ZipFile.(ZipFile.java:127)
在 java.util.zip.ZipFile.(ZipFile.java:143)

WARN - pi.vfs.impl.jar.JarHandlerBase - error in opening zip file: C:deva-maven-projectpom.xml java.util.zip.ZipException: error in opening zip file at java.util.zip.ZipFile.open(Native Method)
