Could not determine java version from '10.0.1'

[JohnnyBackflip]

Hey,

I installed Ubuntu 18.04 on my pc and after that Java OpenJDK 11 as it's described here , then I got this Error when trying to build the Project:

sudo ./gradlew build -debug
12:58:12.492 [DEBUG] [org.gradle.internal.nativeintegration.services.NativeServices] Native-platform is not available.

It might be that the wrapper is too old to support JDK 10, you should try using gradle directly:

gradle build

Thanks this worked, it starts now but says

curl: (7) Failed to connect to localhost port 8080: Connection refused

when I'm trying the curl example:

sudo curl -XPOST http://localhost:8080/ -d '{"method": "listpeers", "id": 1, "params": {}, "jsonrpc": "2.0"}'

[alecalve]

Are you running the JAR file?

java -jar build/libs/c-lightning-http-rpc-0.1.0.jar -c ~/.lightning/lightning-rpc

You also need to be sure that ~/.lightning/lightning-rpc actually points to the socket file.

[JohnnyBackflip]

I'm doing this because the jar has a different name:

sudo java -jar build/libs/c-lightning-http-rpc-0.1.1-SNAPSHOT.jar -c ~/.lightning/lightning-rpc

~/.lightning/lightning-rpc seems to be be correct

[alecalve]

What's the output you get from running the JAR and running a query against it?

[JohnnyBackflip]

So it turns out that I just confused 2 terminals...
When use the correct one I get this error:

sudo java -jar build/libs/c-lightning-http-rpc-0.1.1-SNAPSHOT.jar -c ~/.lightning/lightning-rpc

Hum, this seems to be quite a hairy one:

I've run it on a Ubuntu variant with no issues, I don't really know what's wrong here.
