Problem setting the classLoader

[marceloemanoel]

Hi. I'm making a gradle plugin to integrate mybatis migrations. After migrating my source code to version version 3.1.0 of mybatis-migrations the same code that worked before the upgrade stopped working. It seems that the new behavior is ignoring my attempt to set the driver classloader as can be seen here

Hi Marcelo,

Thank you for the report.
It seems that a fix for another issue (mybatis/mybatis-3@bc15864) caused this.
I'll see if it's possible to fix this without a regression.

For your information, there is an alternative way to load the driver which works with the current implementation.

• do not set the driver class loader by yourself.
• provide the path to the directory which contains the driver jar as 'driver_path' in your environment properties file.

Regards,
Iwao

Hi Iwao,

Unfortunately my problem can't be fixed with the temporary solution you gave me. 😢 The driver classpath is set by the plugin. It uses the same classpath of the application and it is composed by many directories. I did it like this to eliminate the need to duplicate jar files and to leverage the use of the dependency management the gradle offers.

Thank you for your time,
Marcelo

Hi Marcelo,

It's OK, it should work as you expect (unless it breaks something else).

I have just committed the fix to the core repo and it's included in the latest mybatis-3.2.3-SNAPSHOT.
Could you try it to see if it fixes your problem?
You might have to exclude the mybatis dependency from the migration to use the snapshot version.

Thank you,
Iwao

Hi Iwao
I've updated the code to use the snapshot you've provided me but unfortunately now I'm getting this error instead:

Hi Marcelo,

I didn't realize that migrations-3.1.0 is incompatible with mybatis-3.2.3, sorry.
Could you try migrations-3.1.1-SNAPSHOT ?

Thank you for your time!
Iwao

Hi Iwao,

Not yet :( I keep getting the same error.

Thanks for your help,

Getting closer... ;)
The line numbers in the stacktrace tell that it uses an older mybatis jar being built before the fix.
I'm not familiar with Gradle, but have you tried --refresh-dependencies option?

[marceloemanoel]

Hi Iwao,

here's what I just did:

changed the plugin dependencies to:

mybatis-migrations: 3.1.1-SNAPSHOT
mybatis: 3.2.3-SNAPSHOT

still no luck thou :(

Do you have source jars downloading? Can you open the class in question and see if iwao's changes show up?
Could be a stale snapshot jar

Hi h3adache, unfortunately I don't have the source code. Apparently snapshots are coming only as jars or poms. :(

[h3adache]

It's a gradle option to download sources too. I'll try looking at the source when I get back to a computer

Thank you Tim for your help!
But the snapshot repo may not contain sources jar, I'm afraid.
Please use something like JD-GUI to inspect the JARs.

[harawata]

Marcelo,
Could you try installing migration-3.1.1-SNAPSHOT locally with mybatis-3.2.3-SNAPSHOT as its dependency?

$ git clone https://github.com/mybatis/migrations.git
# edit pom.xml : change mybatis version from 3.2.2 to 3.2.3-SNAPSHOT 
$ cd migrations
$ mvn install -Dmaven.test.skip=true

I couldn't build it myself right now because some apache repo does not respond...
