I have successfully retrieved my package with the metadata api.
If I deploy said package with deployOptions.singlePackage=false, I get a successful deployment, with 0 components deployed. I've also done this with minor changes to an .object file ( added a custom field ) to test changes. Still 0 components deployed, no changes to org.
With singlePackage=true, I get errors of "CustomObject xxxxx was specified in package.xml but was not found in the zipped directory".
Since I packaged the retrieved components in the same directory structure that was retrieved, I would have expected it to be successful. I have also tried other directory structures.
The retrieved directory structure that I zipped and tried to deploy was:
/unpackaged package.xml /objects /permissionsets
with xml files in /objects and /permissionsets. Is this the correct zip directory structure? I'm using .net Compression.Zipped.Create to zip. The source for the zip function is a folder which contains /unpackaged, which results in the zip containing the unpackaged directory.
I'm pretty much stuck with this deploy function. Any suggestions? Would the create(), update() functions be easier to use?
