Robert Scholte updated MEXEC-94:
--------------------------------
Issue Type: Improvement (was: Bug)
> Exec plugin does not work with PowerShell
> -----------------------------------------
>
> Key: MEXEC-94
> URL: https://jira.codehaus.org/browse/MEXEC-94
> Project: Maven 2.x Exec Plugin
> Issue Type: Improvement
> Components: exec
> Affects Versions: 1.2
> Environment: Windows
> Reporter: Peter Johnson
> Priority: Minor
> Attachments: execpatch.zip
>
>
> The exec plugin maps stdin to System.in when it runs a process.
> Unfortunately, if you call PowerShell while remapping stdin, PowerShell never
> exits after it finishes the script and simply waits for the user to enter
> something. Thus if you configure exec to run PowerShell, you have to hit
> enter after PowerShell does its thing to get the Maven build to continue.
> Additionally, it seems that it would be a good idea to provide a mechanism to
> feed canned input to apps that want such input.
> The attached patch adds an inputFile parameter to exec:exec. It accepts two
> keywords: "null" to set stdin to null (which is sufficient to get PowerShell
> to exit properly), "stdin" which is the default and maps System.in to stdin
> (thus retaining the existing functionality). It also accepts a file name, in
> which case the file is mapped to stdin.
> The attached zip file contains the patch (I apologize that I did not provide
> any unit test cases, I wasn't quite sure how to extend the existing unit
> tests). The zip file also contains an Eclipse project that I used to test the
> patch. To test, simply cd to the exectest directory and enter:
> mvn -f pom-default.xml (PowerShell will hang because default is System.in,
> press enter to continue)
> mvn -f pom-default.xml -Dexec.inputFile=null (PowerShell will exit
> automatically)
> mvn -f pom-null.xml (PowerShell will exit automatically)
> mvn -f pom-input.xml (The exec plugin will run the included Java app passing
> the file named 'input' to stdin)
