yup. exactly my point. > On the other hand, I was thinking about developers who have a project in > their eclipse connected to svn (or not) and have a warning that a library is > missing whenever they want to compile (right now, a very rare situation) this would be solved via reflection meaning instantiating classes from a string name and running methods derived from string names as well e.g. like https://stackoverflow.com/questions/3574065/instantiate-a-class-object-with-constructor-that-accepts-a-string-parameter https://stackoverflow.com/questions/1782598/with-java-reflection-how-to-instantiate-a-new-object-then-call-a-method-on-it so in your case (just written, down not compiled) roughly Class<?> cl = Class.forName("com.cadplan.jump.utils.LoadSymbolFiles"); // find constructor with the context argument Constructor<?> cons = cl.getConstructor(WorkbenchContext.class); // this is your instance Object o = cons.newInstance(context); // find & run the method Method method = cl.getDeclaredMethod("start"); method.invoke(o); this way the classes accessed do not have to be present during compile but only during runtime. this may throw a lot of exceptions, so make sure to catch them properly, easiest with one catches all. > I can add a readme text file on SVN>CAD plugin>dist folder explaining that > VertexSymbol.jar library is required to compile better put a howto_compile.txt or such in the src folder ;) where devs will stumble over it. > Best regards > Peppe ditto.. sunny regards from rainy germany, ede > > > Il giorno mer 3 giu 2020 alle ore 22:20 <edgar.sol...@web.de > <mailto:edgar.sol...@web.de>> ha scritto: > > On 03.06.2020 17:32, Giuseppe Aruta wrote: > > Hi all, > > I want to add VertexSymbolsXXX.jar as depency to CAD plugin. > > This is the reason: > > Currently, whenever the user saves a new block (CAD toolbar>Block>Save > > geometry as block) as file, this can be used also as a point/line symbol > > for styling.
