javafx application in maven project
提问by Anton
I have a project with structure like this:
我有一个结构如下的项目：
main-project
-libary-1
-library-2
-i-need-javafx-app-here
main-project
-libary-1
-library-2
-i-need-javafx-app-here
So, i need a JavaFX 2 application in my maven project, and it should use library-1 and library-2 with its dependencies. I can't find any maven archetypes for JavaFX 2 projects and i cand find any adequate information about how i can build JavaFX app by Maven 3. I don't need any deployment to web, it will only desktop app.
因此，我的 Maven 项目中需要一个 JavaFX 2 应用程序，它应该使用 library-1 和 library-2 及其依赖项。我找不到 JavaFX 2 项目的任何 Maven 原型，我可以找到有关如何通过 Maven 3 构建 JavaFX 应用程序的任何足够信息。我不需要任何部署到网络，它只会部署桌面应用程序。
So, can anybody help with this problem?
那么，有人可以帮助解决这个问题吗？
UPD:
更新：
java.lang.NoClassDefFoundError: javafx/application/Application
...
Caused by: java.lang.ClassNotFoundException: javafx.application.Application
exception is occured when i try to run application, which is builded by pgrasway.
java.lang.NoClassDefFoundError: javafx/application/Application
...
Caused by: java.lang.ClassNotFoundException: javafx.application.Application
当我尝试运行由pgras方式构建的应用程序时发生异常。

So I guess you already use Java 7, I d'ont know exactly what you need, for compiling you will need only the dependency to javafx, so in your pom for the javafx app:
所以我猜你已经在使用 Java 7，我不知道你到底需要什么，为了编译你只需要对 javafx 的依赖，所以在你的 javafx 应用程序的 pom 中：
<dependencies>
<dependency>
<groupId>com.oracle</groupId>
<artifactId>javafx</artifactId>
<version>2.0</version>
<systemPath>${javafx.rt.jar}</systemPath>
<scope>system</scope>
</dependency>
</dependencies>
And in your maven settings.xml add (and adapt path to your system):
并在您的 maven settings.xml 添加（并将路径调整到您的系统）：
<profile>
<id>javafx</id>
<activation>
<activeByDefault>true</activeByDefault>
</activation>
<properties>
<javafx.rt.jar>C:\Program Files (x86)\Oracle\JavaFX 2.0 SDK\rt\lib\jfxrt.jar</javafx.rt.jar>
<ant.javafx.jar>C:\Program Files (x86)\Oracle\JavaFX 2.0 SDK\tools\ant-javafx.jar</ant.javafx.jar>
</properties>
</profile>
It should be enough to compile and make jar file... If not tell me and I'll post more info...
编译和制作jar文件应该足够了......如果没有告诉我，我会发布更多信息......

Thank you a lot, this link is helpful. So, now my pom looks like this:
非常感谢，这个链接很有帮助。所以，现在我的 pom 看起来像这样：

So, it is possible to run application from command line "java -jar myapp.jar" now, but i have not tested how it will runs with dependencies.
因此，现在可以从命令行“java -jar myapp.jar”运行应用程序，但我还没有测试它如何在依赖项下运行。

I add another answer because it's a long one, and it shows how I do to also generate a signed jar and a JNLP webstart file.
我添加了另一个答案，因为它很长，它展示了我如何生成一个签名的 jar 和一个 JNLP webstart 文件。
So first I create a certificate to be able to sign the jar (you'll be asked to enter some info, I used "superpass" for the passwords, look where it is used in pom) :
因此，首先我创建一个证书以便能够对 jar 进行签名（您将被要求输入一些信息，我使用“superpass”作为密码，看看它在 pom 中的使用位置）：
cd src/main/java
mkdir jnlp
cd jnlp
keytool -genkey -alias signFiles -keystore keystore.jks
And then I use this pom.xml (which has a parent pom but it doesn't contain anything related to javafx):
然后我使用这个 pom.xml （它有一个父 pom 但它不包含任何与 javafx 相关的东西）：

good luck :)
