Lucas Bajolet	c0e7e7bd3c	hcl2: report error on build without sources ... When a template describes a build block without a source reference, the build should be considered invalid as we won't have a CoreBuild produced as a result of the need to have both. In current versions of Packer, this will produce an error message hinting that nothing will happen because of the lack of either build or source block. This commit takes the defined block, and points out to it as missing a source block as being the reason why nothing is happening, making it clearer what is required for an HCL2 build to be processed.	4 years ago
Lucas Bajolet	a298617ecb	command/build: warn and exit when nothing to build ... When a `packer build' is run on a config that does not define anything to be built, the process would run normally, and only state that no artifacts were produced after builds were run successfully. This is misleading as we reach the end of the command without having a proper warning that nothing was even attempted to be built. This commit adds a warning when that happens, and leaves immediately after.	4 years ago
Megan Marsh	48de1fc7da	allow datasources to use other datasources ... create a null data source for testing. We can choose to document if we want to, but it's a convenience for us add a test to catch cyclic datasource dependency, update tests to include out of order data sources, and update the code to clean up the returned diagnostics generated from the recursive evaluation PR review comments	5 years ago
