如何为NetBeans Java Web App项目添加一个jar文件到Ant，以便它可以在Jenkins上构建？

正如我在my previous question中指出的那样，我正在尝试使用Jenkins CI为NetBeans多层Web应用程序项目建立一个自动构建系统。

我的Ant目标是 clean 和 debug 。清理工作，但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＆＃39;＆＃34;＆＃34; C：\ Program Files（x86）\ Jenkins \ tools \ hudson.tasks.Ant_AntInstallation \ Apache_Ant \ bin \ ant.bat＆＃34; ＆＃34; -Dlibs.MySQLDriver.classpath = C：/ Program Files（x86）/ MySQL / MySQL Connector J / mysql-connector-java-5.1.31-bin.jar＆＃34; ＆＃34; -Dlibs.CopyLibs.classpath = C：/ Program Files / NetBeans 8.0 / java / ant / extra / org-netbeans-modules-java-j2seproject-copylibstask.jar＆＃34; ＆＃34; -Dj2ee.server.home = C：/ Program Files / wildfly-8.1.0.Final＆＃34;干净的调试＆amp;＆amp;退出%% ERRORLEVEL %%＆＃34;＆＃39;

这是我输出的最后一部分:(对我来说最重要的部分）

嗯，重要的是Java编译器无法找到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找到了我需要的jar。 Final.jar

我没有使用Ant构建工具的经验，所以我搜索并发现了很多关于它的内容，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。

目前我的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（已导入）由NetBeans生成（您可能已经知道）并且太大而无法在此处显示，此外我无法更改任何内容，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，我已尝试使用我在此处找到的Ant类加载器：https://stackoverflow.com/a/5116470/2541501 但那里没有运气..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：如何更改我的Ant版本，以便Java编译器不会抱怨缺少包（即丢失jar文件）？

我还担心如果我在build.xml文件中添加任何目标，它可能会与生成的build-impl.xml文件中声明的任何内容冲突。任何人都对此有所了解吗？

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我们项目的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。在此私有目录中，有一个名为 private.properties 的文件。我们从此文件中获取属性并将其复制到Ant Invoke的Properties字段中。现在我们的属性字段如下所示：

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，可以在WildFly中找到RESTful Web服务。因此，我们不需要直接包含RESTful Web服务的jar，我们只需要正确设置WildFly服务器的属性。

回想起来，我想说，为NetBeans项目建立一个自动构建的持续集成系统并不难。现在，下一步还包括项目的自动化测试。
