Defining a local server executable capability fails

Defining a local server executable capability
Local server capabilities are inherited by all local agents. This means that local agents can all make use of the executables installed on the Bamboo server machine.
Before you begin:
If you want to run multiple Maven agents on your local server, you will need to configure repository isolation for your Maven executables. See Configuring repository isolation for Maven executables for details.
To define a new local server executable capability:
Click the icon in the Bamboo header and choose Overview.
Click Server Capabilities in the left navigation panel.
Choose Capability Type > Executable in the 'Add Capability' section at the end of the page.
Select the appropriate type of executable from the Type list.
In the Executable Label field, type a name/label for the executable, which Bamboo presents in the Executable list whenever a Task's executable is configured.
In the Path field, type the appropriate path. This will depend on the Type you selected in the previous step.
Note that for Ant and Maven, Bamboo requires the path to be the location of the executable installation folder.
Click Add.
