document requirements and build procedure

[bertsky]

I understand one needs to install Eclipse and import each of the directories under java? (If so, please make this explicit and prominent in the README. It may sound trivial, but other PRImA components depend on this and have no pre-builts, so non-Java / non-Eclipse developers will already stumble here.)

However, I get the following build errors I am unable to get around:

Project 'PrimaDla' is missing required Java project: 'json-simple-tag_release_1_1_1'

I even cloned https://github.com/fangyidong/json-simple and imported it into Eclipse, checkout out release 1.1.1 and had Eclipse rebuild (after deactivating the tests, which would not compile under OpenJDK 11). But it seems like the exported name is different and I have no idea how to set it to 'json-simple-tag_release_1_1_1 as required by PrimaDla.

Not sure if this is helpful but I use IntelliJ IDEA to build prima-core-libs and adding the json-simple-1.1.1 jar as Library works for me (using Java 1.8 as target).

Will do at some point, thanks

I don't want to get into yet another IDE I don't know well. If @chris1010010 says Eclipse is recommended, Eclipse it is (for me).

and adding the json-simple-1.1.1 jar as Library works for me (using Java 1.8 as target).

No luck with that (or JAR I built from within Eclipse or linking the classes from the json-simple project directly). I have even started fiddling with the destination and package names in json-simple's build.xml but the failing dependency in PrimaDla never goes away. (Plus I have no idea where to look for build artifacts – it's all hidden away in Eclipse.)

That's how I have it set up, if that helps. No time to update documentation or releases right now

It did – thanks!

So I had to change the Projects settings (which is where your published .project configured the json-simple-tag_release_1_1_1 dependency, instead of under Libraries).

prima-core-libs build completely now. On to the prima-gwt-lib problems...

I stumbled over this today, too.

I am not 100% sure about this, due to build problems, but I also think the latest release is outdated and does not contain org.primaresearch.dla.page.io.xml.XmlPageWriter_Alto yet, which is required for building PRImA-Research-Lab/prima-page-converter.

I'll have a look as soon as I can, sorry for that

This build.gradle file seems to do the job at least partly:

plugins {
    id 'java-library'
}
apply plugin: 'eclipse'

sourceSets {
    main {
        java {
          srcDir 'java/PrimaBasic/src'
          srcDir 'java/PrimaDla/src'
          srcDir 'java/PrimaIo/src'
          srcDir 'java/PrimaMaths/src'
        }
    }
}


repositories {
    mavenCentral()
}

dependencies {
    implementation 'com.googlecode.json-simple:json-simple:1.1.1'
}

This builds the project, when using the fix in #11, but does not build 4 JARs as in the releases, but only one - which almost* lets prima-page-converter build.

(* There is another issue I'll investigate later)
