FileNotFoundException when searching for poms for {artifactName}-deps-bom and {artifactName}-parent

[mpeddada1]

Initial investigation of FileNotFoundException:

We recently added logging for exceptions the code was previously silencing them. But I think it is surfacing two issues: 1) It seems to be creating an incorrect pomURL for google-cloud-storage-controland google-cloud-bigtable-stats (e.g. https://repo1.maven.org/maven2/com/google/cloud/google-cloud-storage-control/2.37.0-alpha/ is available on Maven central) 2) It is looking for google-cloud-bigtable-stats-deps-bom:2.39.0 when the latest version I could find on maven central is https://repo1.maven.org/maven2/com/google/cloud/google-cloud-bigtable-stats/2.37.0/. The module was removed from the bom in this PR.

For #1, it looks like this is where the pom is generated:

java-cloud-bom/dashboard/src/main/java/com/google/cloud/tools/opensource/cloudbomdashboard/ArtifactMavenData.java

Lines 269 to 283 in 107b178

	private static String generatePomFileUrl(Artifact artifact) {
	String groupPath = artifact.getGroupId().replace('.', '/');
	return DashboardMain.basePath
	+ "/"
	+ groupPath
	+ "/"
	+ artifact.getArtifactId()
	+ "/"
	+ artifact.getVersion()
	+ "/"
	+ artifact.getArtifactId()
	+ "-"
	+ artifact.getVersion()
	+ ".pom";
	}

The logic to determine the shared dependencies version looks at the parentPath, the pomURL, releasePath and depsBomPath in that order. However, the presence of the parent pom is not always guaranteed and it works fine if the version is found in the parentPath but results in the FileNotFoundException if the parent pom is not found (as seen in the case of google-cloud-storage-control).

@mpeddada1 Didn't you fix this?

@suztomo I have a proposed fix to verify the validity of the url before reading from it: #6564. This should address the issue of the FileNotFoundException being thrown.

However, need to do a bit more investigation to improve the logic further to avoid hardcoding certain suffixes for the pom urls (reference)
