Component org.nuxeo.ecm.platform.commandline.executor.service.CommandLineExecutorComponent
Documentation
The CommandLineExecutor component let you define command line call using the command extension point. You can call those commands with your own arguments like blobs or properties. The result is available in the ExecResult object.
Resolution Order
306
The resolution order represents the order in which this component has been resolved by the Nuxeo Runtime
framework.
You can influence this order by adding "require" tags in your component declaration, to make sure it is resolved after another component.
Start Order
840
The start order represents the order in which this component has been started by the Nuxeo Runtime framework.
This number is interesting to tweak if your Java component interacts with other components, and needs to be started before or after another one.
It can be changed by implementing the method "Component#getApplicationStartedOrder()" on your Java component: components are sorted according to this reference value, in increasing order.
The default value is 1000, and the repository initialization uses number 100. Negative values can also be used.

<extension-point name="environment">
<documentation>
Extension point to contribute environment configuration.
Available options are:
- name: comma-separated string attribute used as the environment parameters scope.
It can be empty to set environment parameters common to all commands, equal to a command name to set parameters
for that command only, or equal to a command line to set parameters common to all commands using that command line.
You can associate multiple commands using a comma as separator.
- workingDirectory: the Folder when command should be executed. Default is the system temporary folder.
- parameters/parameter

example:
<code>
<environment name="aCommandName,aCommandLine">
<parameters>
<parameter name="SOME_VAR">some value</parameter>
</parameters>
</environment>

<extension-point name="command">
<documentation>
Extension point to contribute new commands.
Available options are:
- name: string attribute used as the command identifier.
- enabled: boolean attribute, command is unavailable if false.
- commandLine: the command to execute.
- parameterString: the parameters to pass to the command. Parameters like #{parameter} represents a file. So you
can use either a path to a file or a blob. Parameters like %parameters are literals.
- winParameterString: Same as above but used in windows environments. For instance you have to use double quotes
in windows instead of simple quote.
- winCommand: command to execute specifically for windows. Use commandLine is WinCommand is null;
@since 8.4
- testParameterString: the parameters to pass to the CommandTester. The CommandTester will run the command with
these params
@since 8.4
- winTestParameterString: same as above but used in windows environments.
- tester: name of the CommandTester. The CommandTester defined in commandTester extension point. Default is
DefaultCommandTester, which looks if the command is available.
- readOutput: Boolean, default is true. If false, command output is never read.
- installationDirective: a String that is returned instead of the usual output when the command isn't available.
CommandLine contribution example:
<code>
<command name="myCommand" enabled="true">
<commandLine>commandName</commandLine>
<parameterString> -any -parameters '%specific' %parameters #{blobOrPath}</parameterString>
<winParameterString> -any -parameters "%specific" %parameters " #{blobOrPath}</winParameterString>
<testParameterString> -any -parameters</testParameterString>
<winTestParameterString> -any -specific -windows -parameters</winTestParameterString>
<installationDirective>You need to install commandName.</installationDirective>
</command>

Extension point to contribute new command testers.
It's a class that provides a way to test if a command is installed on the target server OS.
Available options are:
-name: the name of the commandTester.
-class: the class
implementing CommandTester interface.
Command tester contribution example:
<code>
<commandTester name="DefaultCommandTester"
class="org.nuxeo.ecm.platform.commandline.executor.service.cmdtesters.DefaultCommandTester">
</commandTester>
