I decided to use Buildr as my build tool: https://buildr.apache.org/ First, to start with empty target directories, I do: buildr clean Then I: buildr --verbose compile which gives me: (in /Users/cerhov/projects/openz/lofdg/buildr_fdg, development) Compiling buildr_fdg mkdir -p /Users/cerhov/projects/openz/lofdg/buildr_fdg/target/resources mkdir -p /Users/cerhov/projects/openz/lofdg/buildr_fdg/target/resources/com/company cp /Users/cerhov/projects/openz/lofdg/buildr_fdg/src/main/resources/com/company/students.txt /Users/cerhov/projects/openz/lofdg/buildr_fdg/target/resources/com/company/students.txt mkdir -p /Users/cerhov/projects/openz/lofdg/buildr_fdg/target/resources/com/company mkdir -p /Users/cerhov/projects/openz/lofdg/buildr_fdg/target/resources/com mkdir -p /Users/cerhov/projects/openz/lofdg/buildr_fdg/target/resources/com/company cp /Users/cerhov/projects/openz/lofdg/buildr_fdg/src/main/resources/com/company/scores.txt /Users/cerhov/projects/openz/lofdg/buildr_fdg/target/resources/com/company/scores.txt mkdir -p /Users/cerhov/projects/openz/lofdg/buildr_fdg/target/resources/com/company cp /Users/cerhov/projects/openz/lofdg/buildr_fdg/src/main/resources/com/company/behavior.txt /Users/cerhov/projects/openz/lofdg/buildr_fdg/target/resources/com/company/behavior.txt mkdir -p /Users/cerhov/projects/openz/lofdg/buildr_fdg/target/resources/com/company cp

Anyone can Help me to figure out why? java eclipse spring jar classpath share|improve this question edited Jul 23 '14 at 13:03 ebram tharwat 4,49642443 asked Jul 22 '14 at 20:32 user3666635 52 add a comment| 1 Answer 1 active oldest votes up vote 0 down vote accepted Problem solved. I am not sure if it is the limitation of classpath size in MAINFEST file, but it really matters when it was too long, I changed all jar name as 1, 2 , 3... and be able to put all jars in the classpath, and it works. Please leave your comments if you have different opinion on this, Thanks. share|improve this answer answered Jul 23 '14 at 12:57 user3666635 52 add a comment| Your Answer draft saved draft d

Do simple GET for example ligustah commented Feb 12, 2016 I encountered the same problem when trying to run Maven, which I manually installed into a node container. It's not really breaking anything for me, just happened to stumble upon java unexpected error this issue. Iron.io member treeder commented Feb 12, 2016 Need example code to reproduce. nikhilm commented Feb 12, 2016 @ivpusic The ca-certificates are installed on the alpine image. I tried hitting https://google.com with a basic Java client and that worked. What URL are you trying to reach? Are you changing any SSL params or using a non-default keystore? ivpusic commented Feb 12, 2016 How to reproduce: import com.mashape.unirest.http.Unirest; import com.mashape.unirest.http.exceptions.UnirestException; /* * This Java source file was auto generated by running 'gradle buildInit --type java-library' * by 'ben' at '2/6/16 8:39 PM' with Gradle 2.10 * * @author ben, @date 2/6/16 8:39 PM */ public final class Library { public final static void main(String[] args) throws UnirestException { System.out.println(Unirest.get("https://www.google.de").asString().getStatus()); } } All default settings. nikhilm commented Feb 12, 2016 Thanks for the info Ivan. As I'm not a Java dev, I'm having trouble with installing dependencies. How does one install Unirest in these Docker images? Is there a simple maven command or something I can run in the same docker container? Thanks. … On Fri, Feb 12, 2016 at 12:07 PM, Ivan Pusic ***@***.***> wrote: Here is example code: import com.mashape.unirest.http.Uni
