我如何为NetBeans Java Web应用程序项目添加一个Java文件到Ant，以便它在Jenkins上构建



正如我在之前的问题中指出的那样，我正在尝试为NetBeans多层web应用程序项目设置一个带有Jenkins CI的自动构建系统。

我的Ant目标是clean和debug。Clean工作正常，但在尝试编译项目时调试失败。

在我的Jenkins构建的输出中，我看到以下命令:

[PGB Webapp] $ cmd.exe/C '"C:Program Files (x86)Jenkinstoolshudson.tasks.Ant_AntInstallationApache_Antbinant.bat" "- dlib . mysqldriver . C '"classpath=C:/Program Files (x86)/MySQL/MySQL Connector J/MySQL - Connector -java-5.1.31-bin.jar" "- dlib . copylib .jar"classpath=C:/Program Files/NetBeans 8.0/java/ant/extra/org-netbeans-modules-java-j2seproject-copylibstask.jar" "-Dj2ee.server. jar"家= C://wildfly-8.1.0程序文件。最后的"干净调试"& &;退出% %返回码% % "

这是我输出的最后一部分:(对我来说似乎最重要的部分)

嗯，这里重要的是Java编译器不能定位RESTful Web Services库。我在C:/Program Files/wildfly-8.1.0.Final/modules/system/layers/base/javax/ws/rs/api/main/jaxrs-api-3.0.8.Final.jar.

我没有Ant构建工具的经验，所以我已经搜索并发现了很多关于它，但我似乎无法弄清楚如何添加这个库，以便项目在Jenkins上正确构建。

当前我的build.xml文件如下所示:

<?xml version="1.0" encoding="UTF-8"?>
<project name="pgb" default="default" basedir="." xmlns:ear="http://www.netbeans.org/ns/j2ee-earproject/2">
    <description>Builds, tests, and runs the project pgb.</description>
    <import file="nbproject/build-impl.xml"/>
    <taskdef resource="net/jtools/classloadertask/antlib.xml">
      <classpath>
        <fileset dir="${basedir}/lib" includes="ant-classloader*.jar"/>
      </classpath>
    </taskdef>
    <!--Add jar to the classpath-->
    <classloader loader="system">
      <classpath>
        <fileset dir="${basedir}/lib" includes="jboss-modules.jar"/>
        <fileset dir="${basedir}/lib" includes="jaxrs-api-3.0.8.Final.jar"/>
      </classpath>
    </classloader>
</project>

文件build-impl.xml(这是导入的)是由NetBeans生成的(您可能已经知道)，并且太大而无法在这里显示，此外我无法更改那里的任何内容，因为系统可能会自动更改该文件本身。

无论如何，正如您所看到的，我已经尝试使用我在这里找到的Ant Classloader: https://stackoverflow.com/a/5116470/2541501但是运气不好……我甚至将所需的jar文件添加到项目的lib目录中。

所以，我的问题是:我如何改变我的Ant构建脚本，使Java编译器不抱怨丢失的包(即丢失的jar文件)?

我还担心，如果我在build.xml文件中添加任何目标，它可能与生成的build-impl.xml文件中声明的任何内容冲突。有人知道这个吗?

好的，我的同事发现我们只需要将NetBeans项目的私有属性复制到项目的Jenkins作业的Ant Invoke的properties字段中。

因此，我们的NetBeans项目在nbproject-目录中有一个名为private的目录。在这个private目录中有一个名为private.properties的文件。我们从该文件中获取属性，并将其复制到Ant Invoke的properties字段中。现在我们的Properties字段如下所示: 
libs.CopyLibs.classpath=C:/Program Files/NetBeans 8.0/java/ant/extra/org-netbeans-modules-java-j2seproject-copylibstask.jar
libs.MySQLDriver.classpath=C:/Program Files (x86)/MySQL/MySQL Connector J/mysql-connector-java-5.1.31-bin.jar
j2ee.platform.is.jsr109=true
j2ee.server.domain=C:/Wildfly/standalone
j2ee.server.home=C:/Wildfly
j2ee.server.instance=wildfly-deployer:localhost:8080#standalone&C:\Wildfly

现在我们可以毫无问题地执行所有Ant命令。我们还可以部署通过Jenkins构建的web应用程序。

如果有人想知道，RESTful Web服务可以在WildFly中找到。因此，我们不需要直接包含rest式Web服务的jar，我们所需要的只是为WildFly服务器设置正确的属性。

回想起来，我想说，为NetBeans项目建立一个带有自动构建的持续集成系统并不是那么困难。现在，下一步是包括项目的自动化测试。
