How can I set VM options in a Java Netbeans Platform Modular Project?
提问by Makoto
I have a Netbeans Platform modular project, not a regular Java project. I want to set VM options to increase memory, but under the "properties" dialog, there is no way to do this for a modular Netbeans platform project. This has cost me huge amounts of time and I still have not found a good way to set the VM args.
我有一个 Netbeans 平台模块化项目，而不是一个普通的 Java 项目。我想设置 VM 选项以增加内存，但在“属性”对话框下，对于模块化 Netbeans 平台项目，无法执行此操作。这花费了我大量的时间，而且我仍然没有找到设置 VM 参数的好方法。
Does anyone know how to set VM args using a Netbeans platform modular project, when compiling and running the program in Netbeans 7? Given the amount of trouble, I am almost ready to give up on Netbeans to create modular applications.
在 Netbeans 7 中编译和运行程序时，有谁知道如何使用 Netbeans 平台模块化项目设置 VM 参数？鉴于麻烦的数量，我几乎准备放弃 Netbeans 来创建模块化应用程序。

It is quite easy, in fact. Just modify project.propertiesfile to include the following line:
事实上，这很容易。只需修改project.properties文件以包含以下行：
Edited:
编辑：
run.args.extra=-J-Xmx768m
Of course, you can include any other JVM options there.
当然，您可以在其中包含任何其他 JVM 选项。
Enjoy.
享受。

I was finally able to solve this based on information at http://activeintelligence.org/blog/archive/gephi-increasing-xmx-memory-in-netbeans/
我终于能够根据http://activeintelligence.org/blog/archive/gephi-increasing-xmx-memory-in-netbeans/上的信息解决这个问题
What I did was modify the project.properties file, as JB said, but the correct way to do it was to add a -J before the args. E.g.,
我所做的是修改 project.properties 文件，正如 JB 所说，但正确的方法是在 args 之前添加一个 -J。例如，
run.args.extra=-J-Xms256m -J-Xmx756m
That did it! Not sure why it took 3 months to figure that out. Definitely a fail for the Netbeans documentation. They should really make this editable from the properties menu instead of making users hunt through nondescript config files!
做到了！不知道为什么花了 3 个月的时间才弄明白。Netbeans 文档绝对是失败的。他们真的应该从属性菜单中进行编辑，而不是让用户搜索不起眼的配置文件！

I thought i'll put some contribution on this topic, When I was developing a netbeans platform applicationi also faced the same problem, I added run.args.extra=-J-Xmx768m and updated my project.propertiesfile but it didn't ! But when i added run.args.extra=-J-Xmx768m in my platform.propertiesfile then it worked, again this only works when i was in development environment. When I packeged the application for windows the problem remained same my min heap size was 24m and max is 64m. Then I found out that if I update and add default_options="--branding my_project -J-Xms64m -J-Xmx1G" in my_project.confin my installed directory C:\Program Files\my_project\etc then run my application and checked the ide log i can now see the change. By the way i wasn't lucky enough to see even the run node when i right click and go to the project properties dialogue in netbeans 7.0.1. Its upto netbeans dream team to make us feel lucky.
我想我会在这个主题上做一些贡献，当我开发一个netbeans 平台应用程序时，我也遇到了同样的问题，我添加了 run.args.extra=-J-Xmx768m 并更新了我的project.properties文件，但它没有！但是当我在我的platform.properties文件中添加 run.args.extra=-J-Xmx768m 时，它就起作用了，同样，这只在我处于开发环境中时起作用。当我为 Windows 打包应用程序时，问题仍然相同，我的最小堆大小为 24m，最大为 64m。然后我发现如果我在my_project.conf 中更新并添加 default_options="--branding my_project -J-Xms64m -J-Xmx1G"在我安装的目录 C:\Program Files\my_project\etc 然后运行我的应用程序并检查 ide 日志我现在可以看到更改。顺便说一句，当我右键单击并转到 netbeans 7.0.1 中的项目属性对话框时，我什至没有看到运行节点。它由 netbeans 梦之队让我们感到幸运。

I had this issue and after some digging around and reading a lot of docs I was able to deduce that most of those values were coming from templates in the harness.
我遇到了这个问题，经过一番挖掘和阅读大量文档后，我能够推断出大多数这些值来自工具中的模板。
So if you go to your IDE_home/harness/etc/ you will find the "app.conf" file. This file is renamed during a distro build and the "app.conf" becomes your "application name.conf". Edit this file with the default values you would like in you application.
因此，如果您转到 IDE_home/harness/etc/，您将找到“app.conf”文件。该文件在发行版构建期间被重命名，“app.conf”成为您的“应用程序名称.conf”。使用您希望在应用程序中使用的默认值编辑此文件。
In my case I replaced the line that read: default_options="--branding ${branding.token} -J-Xms24m -Xmx64m" with default_options="--branding ${branding.token} -J-Xms64m -Xmx512m" as my application was needing more memory. By changing the template I dont have to touch every deployment and change the memory CLI for the VM.
在我的情况下，我用 default_options="--branding ${branding.token} -J-Xms64m -Xmx512m" 替换了以下行： default_options="--branding ${branding.token} -J-Xms24m -Xmx64m"我的应用程序需要更多内存。通过更改模板，我不必接触每个部署并更改 VM 的内存 CLI。
Hope this helps!
希望这可以帮助！

For maven projects:
对于 Maven 项目：
As described in this question, you can use etcConfFileparameter of nbm-maven-plugin:
如本问题所述，您可以使用nbm-maven-plugin 的etcConfFile参数：
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>nbm-maven-plugin</artifactId>
<configuration>
<etcConfFile>src/main/resources/app.conf</etcConfFile>
</configuration>
</plugin>

you have to add these lines to your project properties file.
您必须将这些行添加到您的项目属性文件中。
<target name="build-launchers" depends="suite.build-launchers">
<replace file="build/launcher/etc/${app.name}.conf" token="--branding graphsimulator -J-Xms24m -J-Xmx64m" value="--branding graphsimulator -J-Xms128m -J-Xmx512m"/>
</target>

If you want to use Netbeans to set the VM options without bothering about which file to edit, here we go:
如果您想使用 Netbeans 设置 VM 选项而不必担心要编辑哪个文件，请执行以下操作：
Run -> Set project configuration -> VM Options
Add your option in the corresponding text box for example: -Xms10m
在相应的文本框中添加您的选项，例如：-Xms10m
