Bitbucket - get commited file content

Miś Ursowicz

Hello 

Is there a way to have a conditional merge check script which would check if variable X defined in the committed application.properties file is equal to its counterpart variable X' in the master application.properties file.

Hello,

I'm Reece, an engineer working on ScriptRunner for Bitbucket.

It should be possible for you to achieve what you describe by comparing the content of the file on the source branch vs the target branch (master in your case).

Here is some example code that you could use in a conditional merge check to do this:

import com.atlassian.bitbucket.content.ContentService
import com.atlassian.sal.api.component.ComponentLocator
import com.atlassian.bitbucket.hook.repository.PullRequestMergeHookRequest

def contentService = ComponentLocator.getComponent(ContentService)
def pullRequest = (hookRequest as PullRequestMergeHookRequest).pullRequest

def file = "application.properties"

def sourceBranchFileStream = new ByteArrayOutputStream()
contentService.streamFile(repository, pullRequest.fromRef.id, file, { sourceBranchFileStream })

def targetBranchFileStream = new ByteArrayOutputStream()
contentService.streamFile(repository, pullRequest.toRef.id, file, { targetBranchFileStream })

def sourceBranchProperties = new Properties()
sourceBranchProperties.load(new ByteArrayInputStream(sourceBranchFileStream.toByteArray()))

def targetBranchProperties = new Properties()
targetBranchProperties.load(new ByteArrayInputStream(targetBranchFileStream.toByteArray()))

def nonMatchingProperty = sourceBranchProperties.findResult {
if (targetBranchProperties.get(it.key) != it.value) {
return it
}

null
}

if (nonMatchingProperty) {
return true
}

false

 

The above snippet takes the content of the file application.properties from the source branch, and compares it to the contents of the target branch, this is done by constructing a Properties instance and then comparing the entries.

The above snippet can only be configured by a global administrator, as it uses ContentService and this is not available in hooks configured at the repository level by a repository administrator.

If you have any further questions please let me know.

Kind regards,

Reece
