问题
I have quite complicated ant task to write. I had to make separate builds files and 1 left. There are 4 files:
buildpackage.bat, buildpackage.xml, buildpackage.txt, structure.xml
buildpackage.bat is just an ant file that calls buildpackage.xml "ant -f buildpackage.xml". That is fine.
buildpackage.txt is simple and has got comma-separated lines:
server1,client1
server2,client2
genericserver,client[x]
server[x],client[x]
There is always server name and client name:
Server namecan be letters only, numbers and letters but has variable length.Client name- letters only.
I need to split those files into 2 separate variables: server.name and client.name.
What I have done is:
<loadfile property="buildpackage" srcFile="buildpackage.txt"/>
<for list="${buildpackage}" param="depl.det" delimiter="${line.separator}">
<sequential>
<echo>
Input: @{deploy.details}
</echo>
</sequential>
</for>
The results I get are:
[echo] Input: server_01,Client_01
[echo] Input: server_02,Client_02
[echo] Input: server_03,Client_03
[echo] Input: clientserver,client_04
I would like server_01 to be parameter1 and client_02 to be parameter2.
I will perform other tasks in a sequence. I will copy files from client[x] directory to server[x] (that is simple but how do I split that string into 2 separate variables?).
And now the very complicated task.
I also have structure.xml file. The structure is:
<core>
<clients>
<client>
<name>Client_01</name>
<branding>brand_01</branding>
<applications>
<application>application_01</application>
</applications>
<solutions>
<solution>solution01</solution>
</solutions>
</client>
<client>
<name>Client_07</name>
<branding>brand_09</branding>
<applications>
<application>application_03</application>
</applications>
<solutions>
<solution>solution01</solution>
<solution>solution07</solution>
<solution>solution08</solution>
</solutions>
</client>
<clients>
<core>
I have plenty of clients, applications, brandings, solutions. Each client can have only 1 application and 1 branding but multiple solutions.
Based on previous sequential task (get server and name) I have to loop through that xml file and get for each matching client (from previous task)
- branding
- application
- solutions (multiple or one)
I can read XML using <xmlproperty> but I do not know how to do it sequentially (iterate) and get matching properties.
I know it is complicated. The summary is:
- build script starts
- build script extracts data from buildpackage.txt as client.name and server.name
- build script gets
${client.name}from step 2 as a parameter and loops through structure.xml. It finds matching branding/application/solutions and outputs it for each matching client.
Output:
server.name
client.name
branding.name
application name
solution [X]
solution [y]
Ant has to be processed for each server/client. I can do the rest of the build and compile if I have the properties. I can not touch structure.xml. I can do all I need/want to buildpackage.cml and buildpackge.txt. Buildpackage.txt could be replaced by .xml file or any file (for example .properties). It has to contain those 2 values server and client.
Thank you for your help.
EDIT
Now i have a problem.
If I put same application 2x into a buildfile it builds only first one.
Here is my build.xml file

And if I try yo build buildpackage.txt file
client1=server1
client2=server1
client1=server2
I do get client1->server1, client2->server1 but ...... no client 1to server2
EDIT2
All fixed. The solution for scp task is:
<!-- scp file to remote server -->
<property name="scp_username" value="XXX"/>
<property name="scp_password" value="YYY"/>
<property name="scp_remote_directory" value="path"/>
<for list="${@{client}}" delimiter="=" param = "val">
<sequential>
<property name="token" value="@"/>
<scp trust="true" verbose="true" localFile="${dest.dir}/@{client}/@{client}.zip" remoteTodir="${scp_username}:${scp_password}${token}@@{val}:${scp_remote_directory}"/>
</sequential>
</for>
All works. Thank you for your help
回答1:
For any xmldriven build i recommend using the ant addon xmltask, so something like :
(assuming that clientnames are similar in buildpackage.txt and structure.xml - your snippet has several names Client_01, client1 .. !?)
<project>
<!-- Import XMLTask -->
<taskdef name="xmltask" classname="com.oopsconsultancy.xmltask.ant.XmlTask"/>
<!-- make buildpackage.txt a valid propertyfile to get the job done
f.e. server1,client1 will get client1=server1 etc. ..
to make server easily accessible within xml loop
-->
<replaceregexp
file="buildpackage.txt"
match="(.+),(.+)"
replace="\2=\1"
byline="true" />
<!-- now load that file -->
<property file="buildpackage.txt"/>
<!-- loop over all clients -->
<xmltask source="structure.xml">
<call path="//client">
<param path="name/text()" name="client"/>
<param path="branding/text()" name="branding"/>
<param path="applications/application/text()" name="application"/>
<!-- inside action adress params with @{..} syntax ! -->
<actions>
<!-- the copy (or whatever) action
here demonstrated with echoxml -->
<echoxml>
<!-- access the corresponding server (set via buildpackage.txt)
with nested ${@{..}} syntax ! -->
<copy todir="//${@{client}}/share">
<fileset dir="@{client}/somedir"/>
</copy>
</echoxml>
<echo>${@{client}}${line.separator}@{client}${line.separator}@{application}${line.separator}@{branding}</echo>
<!-- another nested xmltask for loop over solutions -->
<xmltask source="structure.xml">
<call path="//client[name/text()='@{client}']/*/solution">
<param path="text()" name="solution"/>
<actions>
<echo>@{solution}${line.separator}</echo>
</actions>
</call>
</xmltask>
</actions>
</call>
</xmltask>
</project>
If possible you should create buildpackage.txt as valid propertyfile
with the format => Client[x]=Server[x] right away.
Then all you need is the xmltask. Put all your steps to be done into the nested action section as demonstrated with echoxml/copy.
Output :
<?xml version="1.0" encoding="UTF-8"?>
<copy todir="//server1/share">
<fileset dir="client1/somedir" />
</copy>
[echo] server1
[echo] client1
[echo] application_03
[echo] brand_01
[echo] solution01
<?xml version="1.0" encoding="UTF-8"?>
<copy todir="//server4/share">
<fileset dir="client4/somedir" />
</copy>
[echo] server4
[echo] client4
[echo] application_03
[echo] brand_09
[echo] solution01
[echo] solution07
[echo] solution08
BUILD SUCCESSFUL
-- EDIT after question about conditional action, only if ${@{client}} is set --
if propertyfile buildpackage.txt contains wrong properties, means server=client instead of client=server, f.e. :
Sol-e-45-D=PRODUCTION1
CONNECTION=PRODUCTION3
PRODUCTION4=DFHH
PRODUCTION5=MEGA-5
you need some if isset logic. The best is to use the new if/unless feature (introduced with ant191) if you're on ant >= 1.9.3, f.e. :
<!-- you need to activate that feature via namespaces -->
<project
xmlns:if="ant:if"
xmlns:unless="ant:unless"
>
<!-- Import XMLTask -->
<taskdef name="xmltask" classname="com.oopsconsultancy.xmltask.ant.XmlTask"/>
<!-- load propertyfile with client=server mappings -->
<property file="buildpackage.txt"/>
<!-- loop over all clients -->
<xmltask source="structure.xml">
<call path="//client">
<param path="name/text()" name="client"/>
<param path="branding/text()" name="branding"/>
<param path="applications/application/text()" name="application"/>
<!-- inside action adress params with @{..} syntax ! -->
<actions>
<!-- the copy (or whatever) action
here demonstrated with echoxml -->
<echoxml if:set="@{client}">
<!-- access the corresponding server (set via buildpackage.txt)
with nested ${@{..}} syntax ! -->
<copy todir="//${@{client}}/share">
<fileset dir="@{client}/somedir"/>
</copy>
</echoxml>
<echo if:set="@{client}">${@{client}}${line.separator}@{client}${line.separator}@{application}${line.separator}@{branding}</echo>
<!-- another nested xmltask for loop over solutions -->
<xmltask source="structure.xml">
<call path="//client[name/text()='@{client}']/*/solution">
<param path="text()" name="solution"/>
<actions>
<echo if:set="@{client}">@{solution}${line.separator}</echo>
</actions>
</call>
</xmltask>
</actions>
</call>
</xmltask>
</project>
Note => the xmltask call has also an if attribute, but the clientname is not known when starting the loop, can't use <call path="//client" if="@{client}">
output :
<?xml version="1.0" encoding="UTF-8"?>
<copy todir="//PRODUCTION1/share">
<fileset dir="Sol-e-45-D/somedir" />
</copy>
[echo] PRODUCTION1
[echo] Sol-e-45-D
[echo] Sol-e-45-D
[echo] Branding-BLUE
[echo] Sol-e-45-D
<?xml version="1.0" encoding="UTF-8"?>
<copy todir="//PRODUCTION3/share">
<fileset dir="CONNECTION/somedir" />
</copy>
[echo] PRODUCTION3
[echo] CONNECTION
[echo] Sol-e-45-D
[echo] Branding-BLUE
[echo] Sol-e-45-D
Otherwise when bound to ant <= 1.9.3 you may use antcontrib if task, as you're already have that taskdef in your snippet :
<if>
<isset property="@{client}"/>
<then>
<!-- ... -->
</then>
</if>
Beware, your antcontrib taskdef definition is wrong !!, the antcontrib.properties contains only taskdefs for ant < 1.6, declare it like that (assuming antcontrib.jar already on path) :
<project xmlns:ac="antlib:net.sf.antcontrib">
<ac:if>
...
or without namespaces :
<project>
<!-- Import AntContrib -->
<taskdef resource="net/sf/antcontrib/antlib.xml"/>
...
