Fail to install any CLI plugin

[c84c]

Thanks in advance for the great work!

I want to install a plugin for the Flogo CLI, but any plugin fails with Error adding plugin: open <GO_BIN_DIR>/flogo: text file busy.
What do I miss in plugins documentation ?

An example:

The error is generated on the following line

cli/commands/pluginhelper.go

Line 108 in 5c3e1e3

err = util.Copy(filepath.Join(cliCmdPath, cliExe), exPath, false)

Thanks for the support!
