Customization -- java.io.IOException: plugins folder cannot be written to

[Manuel Souto Pico]

Preconditions

• OmegaT is installed and the plugins folder (under the user configuration folder) is empty.
• OmegaT version is 5.3.0
• Script version is 0.4.9
• Running on Mac OS 10.13.6 (High Sierra)
• Local version is 51 and remote version is 53 at least.

Steps

Run OmegaT when the customization script is in the application_startup folder or run the customization script manually.

Expected results

The script downloads the jar files and puts them in the plugins folder, which is empty.

Actual results

The script downloads the jar files bundle, unzips it and then says the plugins folder in the user customization folder cannot be written to, and keeps running forever.

The console gives the error below:
