CCNet的整体结构就是一个Xml文档,根元素就是cruisecontrol,具体的代码块如下所示:
- <cruisecontrolxmlns:cb="urn:ccnet.config.builder">
- <projectname="P1">
- <othersettings/>
- </project>
- <projectname="P2">
- <othersettings/>
- </project>
- </cruisecontrol>
<cruisecontrol xmlns:cb="urn:ccnet.config.builder"> ????<project name="P1"> ????????<other settings /> ????</project> ????<project name="P2"> ????????<other settings /> ????</project></cruisecontrol>
其中,命名空间标定了CCNet里面的预处理过程(Preprocessor)。
一、预处理:Preprocessor
预处理里面包含三个主要元素:define、include和scope,define用于定义以后扩展的常量、include用于包含其他文件的类容,而scope用于封装现存的常量的值。
1、define元素
define元素可以用来定义一个预处理(Preprocessor)常量。如下所示:
- <cb:definefoo="bar"/>
<cb:define foo="bar" />
也可以在一行中定义多个常量:
- <cb:definea="1"b="2"c="3"/>
<cb:define a="1" b="2" c="3"/>
还可以定义一个xml段:
- <cb:definename="baz">
- <some_element>
- <some_inner_element/>
- </some_element>
- </cb:define>
<cb:define name="baz"> ?<some_element> ???<some_inner_element/> ?</some_element></cb:define>
任何有效的xml代码元素都可以包含其中,包括元素、属性、文本节点和注释等。
有两种方式来使用定义的常量:文本引用和xml引用
1)、文本引用的方式如下:$(const_name)
如果常量未定义,系统将搜索系统变量来替换;如果系统变量也不存在,将引发错误。
- <pre><code><span><span><cb:define</span><span>foo</span>=<span><span>"</span><span>bar</span><span>"</span></span><span>/></span></span></code>
<pre><code ><span ><span ><cb:define</span> <span >foo</span>=<span ><span >"</span><span >bar</span><span >"</span></span><span >/></span></span></code>
<somexml attr1="$(foo)"/>
<somexml>$(foo)</somexml>
<env dir="$(PATH)"/>
2)、xml引用的方式如下:
如果常量未定义,系统将搜索系统变量来替换;如果系统变量也不存在,将引发错误。
- <cb:definefoo="bar"/>
- <sample>
- <cb:foo/>
- </sample>
<cb:define foo="bar"/><sample> ?<cb:foo/></sample>
其效果是直接替换被引用的值,上面结果如下:
- <sample>
- bar
- </sample>
<sample> ?bar</sample>
3)、常量的嵌套以及参数
常量引用可以嵌套使用,如下所示:
- <cb:definealpha="alphaval"/>
- <cb:definezed="zedval/$(alpha)"/>
- <z>$(zed)</z>
<cb:define alpha="alphaval"/><cb:define zed="zedval/$(alpha)"/><z>$(zed)</z>
在高层次的嵌套时,在cb:varname这种语法中,常量值是可以传递到调用的元素中去的,如下面的例子:
- <cb:definename="beta">
- <hello>
- <cb:gamma/>
- <hiattr1="$(delta)"/>
- </hello>
- </cb:define>
<cb:define name="beta"> ?<hello> ???<cb:gamma/> ???<hi attr1="$(delta)"/> ?</hello></cb:define>
此时的gamma和delta都还没有定义
- <cb:betadelta="deltaval">
- <cb:definename="gamma">
- <gamma_element>hi</gamma_element>
- </cb:define>
- </cb:beta>
<cb:beta delta="deltaval"> ?<cb:define name="gamma"> ???<gamma_element>hi</gamma_element> ?</cb:define></cb:beta>
在定义了如下xml段之后,gamma就可以正常被替换了,而且上面没有定义的delta常量,也会通过cb:deta定义的delta常量所替换。最终结果如下:
- <hello>
- <gamma_element>hi</gamma_element>
- <hiattr1="deltaval"/>
- </hello>
<hello> ?<gamma_element>hi</gamma_element> ?<hi attr1="deltaval" /></hello>
2、Scope元素
Scope用于控制预处理定义中的范围,在同一个范围里面不可以定义相同的常量,但是在嵌套的范围里面,可以覆盖外层定义的常量,这一点和程序里面的代码段很像。
如下定义:
- <cb:scopea="a_val"b="b_val">
- <testattr="$(a)"attr2="$(b)"/>
- <cb:scopea="a_val_redefined">
- <testattr="$(a)"attr2="$(b)"/>
- </cb:scope>
- </cb:scope>
<cb:scope a="a_val" b="b_val"> ?<test attr="$(a)" attr2="$(b)"/> ?<cb:scope a="a_val_redefined"> ???<test attr="$(a)" attr2="$(b)"/> ?</cb:scope></cb:scope>
其结果为:
- <testattr="a_val"att2="b_val"/>
- <testattr="a_val_redefined"att2="b_val"/>
<test attr="a_val" att2="b_val"/><test attr="a_val_redefined" att2="b_val"/>
其中就覆盖了外层的a常量。
可以将scope应用于CCNet配置文件的Project元素,示例如下:
- <cruisecontrolxmlns:cb="urn:ccnet.config.builder">
- <cb:defineWorkingMainDir="C:\Integration\"/>
- <cb:defineWorkingDir="\WorkingDirectory"/>
- <cb:defineArtifactsDir="\Artifacts"/>
- <cb:scopeProjectName="Alpha">
- <projectname="$(ProjectName)"queue="Q1"queuePriority="1">
- <workingDirectory>$(WorkingMainDir)$(ProjectName)$(WorkingDir)</workingDirectory>
- <artifactDirectory>$(WorkingMainDir)$(ProjectName)$(ArtifactsDir)</artifactDirectory>
- </project>
- </cb:scope>
- <cb:scopeProjectName="Beta">
- <projectname="$(ProjectName)"queue="Q1"queuePriority="1">
- <workingDirectory>$(WorkingMainDir)$(ProjectName)$(WorkingDir)</workingDirectory>
- <artifactDirectory>$(WorkingMainDir)$(ProjectName)$(ArtifactsDir)</artifactDirectory>
- </project>
- </cb:scope>
- </cruisecontrol>
<cruisecontrol xmlns:cb="urn:ccnet.config.builder"> ??<cb:define WorkingMainDir="C:\Integration\"/> ??<cb:define WorkingDir="\WorkingDirectory"/> ??<cb:define ArtifactsDir="\Artifacts"/> ???<cb:scope ProjectName="Alpha"> ????<project name="$(ProjectName)" queue="Q1" queuePriority="1"> ??????<workingDirectory>$(WorkingMainDir)$(ProjectName)$(WorkingDir)</workingDirectory> ??????<artifactDirectory>$(WorkingMainDir)$(ProjectName)$(ArtifactsDir)</artifactDirectory> ???</project> ?</cb:scope> ?<cb:scope ProjectName="Beta"> ???<project name="$(ProjectName)" queue="Q1" queuePriority="1"> ?????<workingDirectory>$(WorkingMainDir)$(ProjectName)$(WorkingDir)</workingDirectory> ?????<artifactDirectory>$(WorkingMainDir)$(ProjectName)$(ArtifactsDir)</artifactDirectory> ???</project> ?</cb:scope></cruisecontrol>
而其结果则为:
- <cruisecontrol>
- <projectname="Alpha"queue="Q1"queuePriority="1">
- <workingDirectory>C:\Integration\Alpha\WorkingDirectory</workingDirectory>
- <artifactDirectory>C:\Integration\Alpha\Artifacts</artifactDirectory>
- </project>
- <projectname="Beta"queue="Q1"queuePriority="1">
- <workingDirectory>C:\Integration\Beta\WorkingDirectory</workingDirectory>
- <artifactDirectory>C:\Integration\Beta\Artifacts</artifactDirectory>
- </project>
- </cruisecontrol>
<cruisecontrol> ?????<project name="Alpha" queue="Q1" queuePriority="1"> ??????<workingDirectory>C:\Integration\Alpha\WorkingDirectory</workingDirectory> ??????<artifactDirectory>C:\Integration\Alpha\Artifacts</artifactDirectory> ????</project> ?????<project name="Beta" queue="Q1" queuePriority="1"> ?????<workingDirectory>C:\Integration\Beta\WorkingDirectory</workingDirectory> ?????<artifactDirectory>C:\Integration\Beta\Artifacts</artifactDirectory> ???</project></cruisecontrol>
通过scope,一个变通的定义方式如下:
- <cruisecontrolxmlns:cb="urn:ccnet.config.builder">
- <cb:defineWorkingMainDir="C:\Integration\"/>
- <cb:defineWorkingDir="\WorkingDirectory"/>
- <cb:defineArtifactsDir="\Artifacts"/>
- <cb:definename="OurProject">
- <projectname="$(ProjectName)"queue="Q1"queuePriority="1">
- <workingDirectory>$(WorkingMainDir)$(ProjectName)$(WorkingDir)</workingDirectory>
- <artifactDirectory>$(WorkingMainDir)$(ProjectName)$(ArtifactsDir)</artifactDirectory>
- </project>
- </cb:define>
- <cb:scopeProjectName="Alpha">
- <cb:OurProject/>
- </cb:scope>
- <cb:scopeProjectName="Beta">
- <cb:OurProject/>
- </cb:scope>
- </cruisecontrol>
<cruisecontrol xmlns:cb="urn:ccnet.config.builder"> ?<cb:define WorkingMainDir="C:\Integration\"/> ?<cb:define WorkingDir="\WorkingDirectory"/> ?<cb:define ArtifactsDir="\Artifacts"/> ??<cb:define name="OurProject"> ???<project name="$(ProjectName)" queue="Q1" queuePriority="1"> ?????<workingDirectory>$(WorkingMainDir)$(ProjectName)$(WorkingDir)</workingDirectory> ?????<artifactDirectory>$(WorkingMainDir)$(ProjectName)$(ArtifactsDir)</artifactDirectory> ??</project> </cb:define> <cb:scope ProjectName="Alpha"> ??<cb:OurProject/> </cb:scope> <cb:scope ProjectName="Beta"> ??<cb:OurProject/> </cb:scope></cruisecontrol>
这样则较大的提高了配置的可维护性。
3、include元素
include元素用来包含其他的文件内容,include中根据ccnet.config文件为基准路径进行相对定位,这样就可以在ccnet.config文件里面调用所有其他文件定义的部分,以提高可维护性。如下所示:
- <cruisecontrolxmlns:cb="urn:ccnet.config.builder">
- <cb:includehref="Definitions.xml"xmlns:cb="urn:ccnet.config.builder"/>
- <cb:includehref="CI_Projects.xml"xmlns:cb="urn:ccnet.config.builder"/>
- <cb:includehref="QA_Projects.xml"xmlns:cb="urn:ccnet.config.builder"/>
- </cruisecontrol>
<cruisecontrol xmlns:cb="urn:ccnet.config.builder"> ???<cb:include href="Definitions.xml" xmlns:cb="urn:ccnet.config.builder"/> ???<cb:include href="CI_Projects.xml" xmlns:cb="urn:ccnet.config.builder"/> ???<cb:include href="QA_Projects.xml" xmlns:cb="urn:ccnet.config.builder"/> ?</cruisecontrol>
其中Definitions.xml文件定义如下:
- <cb:config-templatexmlns:cb="urn:ccnet.config.builder">
- <queuename="Q1"duplicates="UseFirst"lockqueues="Q2,Q4"/>
- <cb:definename="EmailPublisher">
- <emailfrom="buildmaster@mycompany.com"
- mailhost="localhost"
- mailhostUsername="TheMailer"
- mailhostPassword="JohnWayne"
- includeDetails="TRUE">
- <users/>
- <groups/>
- <modifierNotificationTypes>
- <NotificationType>Failed</NotificationType>
- <NotificationType>Fixed</NotificationType>
- </modifierNotificationTypes>
- </email>
- </cb:define>
- <cb:definename="common_publishers">
- <artifactcleanupcleanUpMethod="KeepMaximumXHistoryDataEntries"cleanUpValue="500"/>
- <xmllogger/>
- <statistics/>
- <modificationHistoryonlyLogWhenChangesFound="true"/>
- <rss/>
- </cb:define>
- <cb:definename="common_nant">
- <executable>c:\nant\nant.exe</executable>
- <nologo>true</nologo>
- <buildTimeoutSeconds>240</buildTimeoutSeconds>
- </cb:define>
- <cb:definename="nant_args_CI">
- <buildArgs>cleancompile</buildArgs>
- </cb:define>
- </cb:config-template>
<cb:config-template xmlns:cb="urn:ccnet.config.builder"> ?<queue name="Q1" duplicates="UseFirst" lockqueues="Q2, Q4" /> ?<cb:define name="EmailPublisher"> ???<email from="buildmaster@mycompany.com" ??????????mailhost="localhost" ??????????mailhostUsername="TheMailer" ??????????mailhostPassword="JohnWayne" ??????????includeDetails="TRUE"> ???<users /> ???????<groups /> ???????<modifierNotificationTypes> ?????????<NotificationType>Failed</NotificationType> ?????????<NotificationType>Fixed</NotificationType> ???????</modifierNotificationTypes> ???</email> ?</cb:define> ?<cb:define name="common_publishers"> ???<artifactcleanup cleanUpMethod="KeepMaximumXHistoryDataEntries" cleanUpValue="500" /> ???<xmllogger /> ???<statistics /> ???<modificationHistory ?onlyLogWhenChangesFound="true" /> ???<rss/> ?</cb:define> ?<cb:define name="common_nant"> ??????<executable>c:\nant\nant.exe</executable> ??????<nologo>true</nologo> ???<buildTimeoutSeconds>240</buildTimeoutSeconds> ?</cb:define> ?<cb:define name="nant_args_CI"> ?????<buildArgs>clean compile</buildArgs> ?</cb:define></cb:config-template>
在Definitions.xml文件里面,需要使用db:config-template作为根元素使用。
