p1_NLCD_data_zipped gets outdated after first run through pipeline

[jds485]

After a 1st tar_make(), three NLCD targets are outdated (image below). When a 2nd tar_make() is called, the first two (zipped and unzipped) are rebuilt, and the last is skipped. After that, tar_make() skips all targets. So, I'm expecting that something in the p1_NLCD_data function is causing the previous two NLCD targets to become outdated. I did not see anything that would cause it, though.

Noting that this should be addressed by the suggested ScienceBase date last modified check in #98.

is this still happening btw?

[jds485]

yes. it happened yesterday when I tested building the full pipeline in the container

I figured out why this is happening: The p1_NLCD2011_data_unzipped target writes an unzipped directory within the p1_NLCD2011_data_zipped output directory, so that causes p1_NLCD2011_data_zipped to become outdated.
