java - 如何将 NetBeans Java Web 应用程序项目的 jar 文件添加到 Ant，以便在 Jenkins 上构建它？

Question

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 应用程序项目设置自动构建系统。

我的 Ant 目标是干净和调试。 Clean 可以工作，但在尝试编译项目时调试失败。

在 Jenkins 构建的输出中，我看到以下命令:

[PGB Webapp] $ cmd.exe/C '""C:\Program Files (x86)\Jenkins\tools\hudson.tasks.Ant_AntInstallation\Apache_Ant\bin\ant.bat""-Dlibs.MySQLDriver.classpath=C:/Program Files (x86)/MySQL/MySQL Connector J/mysql-connector-java-5.1.31-bin.jar""-Dlibs.CopyLib s.classpath=C:/Program Files/NetBeans 8.0/java/ant/extra/org-netbeans-modules-java-j2seproject-copylibstask.jar""-Dj2ee.server.home=C:/Program Files/wildfly-8.1.0.Final"干净调试 && 退出 %%ERRORLEVEL%%"'

这是我输出的最后一部分:(对我来说最重要的部分)

这里重要的是 Java 编译器无法找到 RESTful Web 服务库。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 找到了我需要的 jar。

我没有使用 Ant 构建工具的经验，所以我搜索并找到了很多相关信息，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，此外我无法在那里更改任何内容，因为系统可能会自动更改该文件本身。

无论如何，正如你所看到的，我尝试使用我在这里找到的 Ant 类加载器:https://stackoverflow.com/a/5116470/2541501但运气不佳..我什至将所需的 jar 文件添加到项目的 lib 目录中。

所以，我的问题是:如何更改 Ant 构建脚本，以便 Java 编译器不会提示缺少包(即缺少 jar 文件)？

我还担心，如果我向 build.xml 文件添加任何目标，它可能会与生成的 build-impl.xml 文件中声明的任何内容发生冲突。有人也知道这件事吗？

好吧，我的同事发现我们只需将 NetBeans 项目的私有(private)属性复制到我们项目的 Jenkins 作业的 Ant Invoke 的 Properties 字段即可。

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。所以我们不需要直接包含RESTful Web Services的jar，我们只需要正确设置WildFly服务器的属性即可。

回想起来，我想说，为 NetBeans 项目设置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。
