strdist error message - java.lang.NoSuchMethodError

[sogervais]

Hi. I am getting a java.lang.NoSuchMethodError when using the strdist command from the STRUTIL package.

Thought it was something I was doing at first. I did a complete reinstall and the phonetic encoding commands continue to work fine. However the strdist command returns this error. I've recreated it below with your example.

` sysuse census
(1980 Census data by state)

. keep state state2

. strdist state state2, jarowinklers(jaro_sim)

This error is occurring on a PC - recent upgrade on my work machine.
I've not had the error on my mac - STRUTIL was installed last year when I first discovered your program and all is working ok on that installation.

I see from this exchange wbuchanan/StataJSON#22 that a similar error occured perhaps due to a dependency issue with StataJavaUtilities. Perhaps this is another in the same vein.

I hope this is something you can easily address.

That definitely seem to be the culprit. In the pom file you'll see this towards the very end:

<dependency>
			<groupId>org.paces-consulting</groupId>
			<artifactId>stata-java</artifactId>
			<version>0.0.3-SNAPSHOT</version>
			<type>jar</type>
			<scope>compile</scope>
			<optional>false</optional>
		</dependency>

That is basically packaging the StataJavaUtilities binary in the contents of the StataStringUtilities binary as well. This should be a relatively easy file (e.g., should just need to recompile the binary with a modification to the scope of the StataJavaUtilities dependency as provided). My access to a PC is fairly limited, but if you can let me know if you have any of my other programs that have Java binaries associated with them installed on your PC I can try to ask one of the folks in my shop to test things quickly.

The dependency for StataJavaUtilities should read:

		<dependency>
			<groupId>org.paces-consulting</groupId>
			<artifactId>stata-java</artifactId>
			<version>0.0.3-SNAPSHOT</version>
			<type>jar</type>
			<scope>provided</scope>
			<optional>false</optional>
		</dependency>

That should basically tell the JVM to look for the StataJavaUtilities library on the end user's system instead of packaging it with this program.

I just recompiled with the change mentioned above and tried pushing an update to the distribution page. If you could try reinstalling the package from the GitHub page:

net inst strutil, from(http://wbuchanan.github.io/StataStringUtilities) replace force

That should fix things (hopefully). If it does, definitely let me know and if it is still issuing the same error I'll try to spend a bit more time digging into this issue over the weekend to try fixing it.

I had to play around with my windows setup a bit and now it works.

I removed both the STRUTIL and BREWSCHEME packages that I had installed. I had not yet added an ado/personal folder. Reinstalled BREWSCHEME and then STRUTIL and now I am up and running.

Thanks for getting to this so quickly. I really appreciate the support!

Awesome. Glad to hear it fixed things on your end as well.
