[luongnhattruong]

Context: When i export data to MSSQL with driver options {password=***, user=xxx, authentication=ActiveDirectoryPassword} i got exception

com.microsoft.sqlserver.jdbc.SQLServerException: Failed to load ADAL4J Java library for performing ActiveDirectoryPassword authentication.

Purpose: Support jdbc option authentication=ActiveDirectoryPassword

@luongnhattruong It looks to be the same purpose with embulk/embulk-input-jdbc#230, then it basically looks good to me. However, can you :

1. Leave more background in the pull-req description?
2. Add a comment in build.gradle so that this adal4j is required for this purpose?
3. Explain why did you choose the verison 1.6.3?
   • i.e. Add adal4j to support active directory authentication embulk-input-jdbc#230 seems to have a newer version 1.6.7 while it was a pull-req in 2022.

@dmikurube ,
I have updated context for this PR in description for 1
I choose version 1.6.3 due to https://learn.microsoft.com/en-us/sql/connect/jdbc/feature-dependencies-of-microsoft-jdbc-driver-for-sql-server?view=sql-server-ver16

JDBC Driver version 7.2.2—Dependency versions: Adal4j (version 1.6.3), Client-Runtime-for-AutoRest (1.6.5), and their dependencies

We are using :

implementation 'com.microsoft.sqlserver:mssql-jdbc:7.2.2.jre8'

Okay, however, my two cents on that we will forget that adal4j is there to couple with mssql-jdbc (for that purpose of ActiveDirectoryPassword) when we have to upgrade mssql-jdbc in the future.

To avoid an expected future mistake, please also add :

• more explanation that adal4j is there to couple with the proper version of mssql-java for Azure Active Directory Authentication
• more explanation that adal4j just needs to be there in the classpath without any reference from the plugin code, and it should not be removed even if it still compiles even if adal4j is removed
  • when we consider removing "unnecessary libraries" in the future, we may consider it can be removed because removing it won't make the compilation fail.
