背景
我在本地桌面上运行的两个虚拟机上构建了一个持续集成系统。VM #1 ( Toolbox ) 正在运行 CruiseControl.Net、Subversion、BugTracker.Net 和 SQL Server Express。VM #2 ( BuildMaster ) 使用 NAntContrib 运行 NAnt,并安装了 VB 6.0 和 1.0/1.1/2.0/3.5 .Net Framework SDK。其目的是严格控制 BuildMaster 上安装的内容,并在 Toolbox 和开发人员工作站上更加宽松。
问题
我在 Toolbox 上有一个 CCNet 项目,它成功地在 BuildMaster 上编译了一个测试 VB 6.0 应用程序,但是上周构建开始失败。我记得做的唯一一件事就是在 Toolbox 上安装 BugTracker.Net 和 SQL Server Express。
症状
构建失败并返回异常:
<![CDATA[Starting 'vb6 ( /make "\\buildmaster\Working\TestApp\TestApp.vbp" /outdir "\\buildmaster\Working\TestApp\build" /out "\\buildmaster\Working\TestApp\TestApp.build.err")' in '\\buildmaster\Working\TestApp']]></message><duration>711.02240000000006</duration></task><duration>761.09440000000006</duration></target><failure><builderror><type>NAnt.Core.BuildException</type><message><![CDATA['vb6' failed to start.]]></message><location><filename>\\buildmaster\Working\TestApp\TestApp.build</filename><linenumber>39</linenumber><columnnumber>4</columnnumber></location><stacktrace><![CDATA[ at NAnt.Core.Tasks.ExternalProgramBase.StartProcess() in c:\Nant\src\NAnt.Core\Tasks\ExternalProgramBase.cs:line 501

显然,异常的核心是[CDATA['vb6' failed to start.]]。我的问题是,当我直接在 BuildMaster 上运行 Nant 构建时,它每次都会成功完成构建。
为了完整起见,这是我的 NAnt 构建脚本:
<?xml version="1.0" ?>
<project name="TestApp" default="build">
<!-- set build.date property to current date in format yyyy-MM-dd -->
<tstamp property="build.date" pattern="yyyy-MM-dd" />
<!-- global project settings -->
<property name="project.name" value="TestApp" />
<property name="project.version" value="1.00" unless="${property::exists('project.version')}" />
<property name="project.release.type" value="release" unless="${property::exists('project.release.type')}" /> <!-- nightly / dev / alpha / beta# / rc# / release -->
<property name="build.warnaserror" value="false" />
<!-- default configuration -->
<property name="project.client" value="" />
<property name="build.defines" value="" />
<property name="build.number" value="${math::abs(math::floor(timespan::get-total-days(datetime::now() - datetime::parse('01/01/2000'))))}" />
<!-- platform specific properties. These are the defaults -->
<property name="current.build.defines" value="${build.defines}" />
<!-- Build Tasks -->
<target name="init" description="Initializes build properties">
<property name="build.dir" value="${project::get-base-directory()}\build" />
<echo message="Build Directory is ${build.dir}" />
</target>
<target name="clean" depends="init" description="Deletes current build configuration">
<echo message="Clearing out files before recompiling..." />
<delete verbose="true">
<fileset basedir="${build.dir}">
<include name="TestApp*.exe" />
</fileset>
</delete>
</target>
<target name="build" depends="clean" description="Perform a build of the base TestApp product">
<mkdir dir="${build.dir}" unless="${directory::exists(build.dir)}" />
<!-- Actually compile VB6 project into executable -->
<vb6 project="TestApp.vbp" outdir="${build.dir}" errorfile="TestApp.build.err" verbose="true" />
</target>
</project>
非常感谢您的帮助!
