OSM Import plugin generation error

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.

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.

Are there more details to the error message?

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.

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

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 \
       --skip-duplicate-nodes --delete --into target/databases/map2 samples/map2.osm.bz2

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

Oh if you are on windows?

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

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

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
