Package Errors

[Pardheev Krishna Tammineni]

I recently downloaded a code from the cpsolver repository on GitHub and attempted to run it on my system. However, I encountered some package errors that are hindering the execution. I am seeking assistance from the community to resolve these issues.
Details:
1. Code Repository: https://github.com/UniTime/cpsolver
2. Error Messages:
3. Steps to Reproduce: Tried running the IFS examples https://github.com/UniTime/cpsolver/blob/master/src/org/cpsolver/ifs/example/csp/Test.java

I appreciate any assistance or guidance the community can provide.
Thank you in advance!

Dear Pardheev,

The CPSolver can be built using Apache Ant or Maven.

First, you need to clone the Git repository:

git clone https://github.com/UniTime/cpsolver.git

Second, to build using Maven, execute mvm package in the cpsolver folder

cd cpsolver

mvn package

The resultant JAR is placed in the target folder: target/cpsolver-1.4-SNAPSHOT.jar. It is also included inside of the target/cpsolver-1.4-SNAPSHOT-dist.zip distribution.

Or using Apache Ant calling ant in the cpsolver filter (root folder of the cpsolver repository):

cd cpsolver

ant

 

Buildfile: /users/muller/test/cpsolver/build.xml

clean:

init:
    [mkdir] Created dir: /Users/muller/Test/Build/cpsolver/tmp
    [mkdir] Created dir: /Users/muller/Test/Build/cpsolver/dist/bin
     [echo] Source files: /Users/muller/Test/Build/cpsolver/src
     [echo] Libs: /Users/muller/Test/Build/cpsolver/lib
...

dist:
    [mkdir] Created dir: /Users/muller/Test/Build/cpsolver/dist/lib
     [copy] Copying 3 files to /Users/muller/Test/Build/cpsolver/dist/lib
      [zip] Building zip: /Users/muller/Test/Build/cpsolver/dist/cpsolver-1.4_bld1.zip

The resultant JAR is under dist/bin/cpsolver-all-1.4.jar (or inside of the dist/cpsolver-1.4_bld1.zip).

For running the example, please place the cpsolver library in the same folder as the dependencies (dom4j-2.1.4.jar, log4j-api-2.20.0.jar, log4j-core-2.20.0.jar -- these are also included in the distribution zip file). For example:

java -Xmx1g -cp cpsolver-1.4-SNAPSHOT.jar org.cpsolver.ifs.example.csp.SimpleTest

Alternatively, you can include all the dependencies in the classpath. For example (using the locations from the Git repository and Maven build):

java -Xmx1g -cp target/cpsolver-1.4-SNAPSHOT.jar:lib/dom4j-2.1.4.jar:lib/log4j-api-2.20.0.jar:lib/log4j-core-2.20.0.jar org.cpsolver.ifs.example.csp.SimpleTest

java -Xmx1g -cp target/cpsolver-1.4-SNAPSHOT.jar:lib/dom4j-2.1.4.jar:lib/log4j-api-2.20.0.jar:lib/log4j-core-2.20.0.jar org.cpsolver.ifs.example.csp.Test csp-example.cfg

See the attached configuration csp-example.cfg.

Best regards,

Tomas Muller
