I tried below
Read resolve did not seem to be working with this scenario. i may not be
doing things rite . i tried below
protected Object ReadResolve() {
if(matlabRoot != null) {
MatlabInstallation matlab = new MatlabInstallation("default",
matlabRoot, null, false, false);
this.setMatlabRoot(matlab.getHome());
}
return this;
}
Where :
*matlabRoot is my old field which i want to add it as installation section
by name default and populate this default in my build step instead of
matlabRoot*
