OSM Import plugin generation error

[kimmo_wiltshire]

I've been trying to install the newer OSM import plugin for neo4j. using the maven clean intstall (have tried using maven 3.6.1 and 3.6.1/ java jdk 11.0.3 and 12.0.1)running into a build error:

'The code being documented uses modules but the packages defined in http://docs.oracle.com/javase/7/docs/api/ are in the unnamed module.'

Not really neo4j but I'm not a Java developer. Anyone know how to fix this.?

Thanks!

Try it with java 8, that should work.

[kimmo_wiltshire]

Thanks for that! That worked fine, using Java 8. However, I'm now trying to import an OSM file... trying to follow the instructions on Git..I take it I just run these through the windows command prompt with my path values for target database and source files replaced...it's not working falls over with first error ...Error: Could not find or load main class \ ??? have no idea how to proceed. Any direction would be most appreciated. Thanks.

[michael_hunger]

Are there more details to the error message?

[kimmo_wiltshire]

Hi,I've tried regigging the paths ; the last full error is:

Error: Could not find or load main class \

What was the command line you ran.

[kimmo_wiltshire]

exactly as is on git for the sample. looks like at the files etc are there:

  java -Xms1280m -Xmx1280m \
-cp "target/osm-0.2.2-neo4j-3.5.1.jar:target/dependency/*" org.neo4j.gis.osm.OSMImportTool \
--skip-duplicate-nodes --delete --into target/databases/map2 samples/map2.osm.bz2

[michael_hunger]

it worked perfectly fine for me

did you perhaps forget to build the project?

mvn clean installmvn clean install dependency:copy-dependencies

java -Xms1280m -Xmx1280m \
       -cp "target/osm-0.2.2-neo4j-3.5.1.jar:target/dependency/*" org.neo4j.gis.osm.OSMImportTool \

Hi again Michael.
Yeap i definitely built it after installing Java 8 - worked fine. There are 4 jar files in the target folder:

osm-0.2.2-neo4j-3.5.1.jar (91KB)

osm-0.2.2-neo4j-3.5.1.-javadoc.jar (149KB)

osm-0.2.2-neo4j-3.5.1.-procedures.jar (92KB)
osm-0.2.2-neo4j-3.5.1.-sources.jar (25KB)

Do these look right to you?

After the build , I did : mvn dependency:copy-dependencies

This built fine I think. Then the remaining code which is where the error is happening. Thanks

[michael_hunger]

Oh if you are on windows?

Try to put everything in one command line and remove the \

[kimmo_wiltshire]

Thanks for that but still not quite working. Yeap, I'm Windows 10 I put:

java -Xms1280m -Xmx1280m -cp "target/osm-0.2.2-neo4j-3.5.1.jar:target/dependency/*" org.neo4j.gis.osm.OSMImportTool --skip-duplicate-nodes --delete --into target/databases/map2 samples/map2.osm.bz2

as one line. It now comes back with 'Error: Could not find or load main class org.neo4j.gis.osm.OSMImportTool"

I can see the OSMImportTool.class file Probably some small other thing..I've tried to search for an answer but no luck to date..is there anything else I need to change?

Thanks

[kimmo_wiltshire · Accepted solution]

Worked out the issue = need to change colon to semi colon in windows

This works java -Xms1280m -Xmx1280m -cp "target/osm-0.2.2-neo4j-3.5.1.jar;target/dependency/*" org.neo4j.gis.osm.OSMImportTool --skip-duplicate-nodes --delete --into target/databases/map2 samples/map2.osm.bz2

I have the same error.
In the /target folder I have the following 4 jars:
osm-0.2.3-neo4j-4.0.9-javadoc.jar
osm-0.2.3-neo4j-4.0.0-sources.jar
osm-0.2.3-neo4j-4.0.0-procedures.jar
osm-0.2.3-neo4j-4.0.0.jar

I see a OSMImportTool.class at osm/target/classes/org/neo4j/gis/osm/OSMImportTool.class

I am on Mac OS X.

Neither with ":" nor ";" nor "" nor on a single line does it work.

Any suggestions?

Edit: Today it worked. I had since restarted my computer, perhaps that did something? Anyways, I got another error, but as soon as I update Java that went away as well. (on Mac it works with ":". So ";" is not required there.

If anybody else has the problem, I'm sorry I don't know why it suddenly worked. Just make sure you're in the /osm root and use the osm-[version-you-have]-neo4j-[version-you-have] and it should work.
