Using Tests Selector plugin to generate a list of test as properties to pass into ant. Hudson/ant quote the arguments incorrect. It put double quotes on the json key/value.

Tried the same test on mac (running hudson on mac), the escaping work correctly.

below....

$ cmd.exe /C '"ant.bat -file build.xml "-DSYS=[

{""enabled"":true,""owner"":""shushu"",""testgroup"":""A"",""testcase"":""single"",""multiplicity"":1}

,

{""enabled"":false,""owner"":""shushu"",""testgroup"":""B"",""setuptype"":""basic"",""testcase"":""triple"",""multiplicity"":1}

]" testManual && exit %%ERRORLEVEL%%"'
Buildfile: D:\Jenkins\workspace\SYS-02-ManualBuild\SYS\build.xml

I echo out the "SYS" property and it contain the following value

[echo] [

{"enabled:true,owner:shushu,testgroup:A,testcase:single,multiplicity:1}

,

{enabled:false,owner:shushu,testgroup:B,setuptype:basic,testcase:triple,multiplicity:1}

] testManual
