java - Create Source Folder Programmatically -

-

i have tried create 1 source folder in java project below code.

    iworkspaceroot root = resourcesplugin.getworkspace().getroot();     iproject project = root.getproject(projectname);     project.create(null);     project.open(null);     iprojectdescription description = project.getdescription();     description.setnatureids(new string[] { javacore.nature_id });     project.setdescription(description, null);     ijavaproject javaproject = javacore.create(project);      ifolder sourcefolder = project.getfolder("src");     sourcefolder.create(false, true, null);     ipackagefragmentroot root = javaproject.getpackagefragmentroot(sourcefolder);     iclasspathentry[] oldentries = javaproject.getrawclasspath();     iclasspathentry[] newentries = new iclasspathentry[oldentries.length + 1];     system.arraycopy(oldentries, 0, newentries, 0, oldentries.length);     newentries[oldentries.length] = javacore.newsourceentry(root.getpath());     javaproject.setrawclasspath(newentries, null);

but giving java model exception last line : javaproject.setrawclasspath(newentries, null);

java model exception: java model status [cannot nest 'projectname/src' inside 'projectname'. enable nesting exclude 'src/' 'projectname']     @ org.eclipse.jdt.internal.core.javamodeloperation.runoperation(javamodeloperation.java:784)     @ org.eclipse.jdt.internal.core.javaproject.setrawclasspath(javaproject.java:3102)     @ org.eclipse.jdt.internal.core.javaproject.setrawclasspath(javaproject.java:3064)     @ org.eclipse.jdt.internal.core.javaproject.setrawclasspath(javaproject.java:3117)

can 1 tell me how can create source folder programmatically?

when called javaproject.getpackagefragmentroot(), created build path project using source folder. skip it, can project-relative path ifolder instance , make newsourceentry that.

i use sonar plugin executes if activated in maven profile. sonar runs on every compile. the problem build fail other team members not have sonar application installed locally. pom.xml checked in team members same copy including sonar configuration, don't want them modify purpose of disabling sonar (they might inadvertently check modified copy in). please advise how configure maven (.m2/settings.xml) and/or pom.xml sonar feature can enabled/disabled local profile. here sonar configuration in each project's pom.xml: <plugin> <groupid>org.codehaus.mojo</groupid> <artifactid>sonar-maven-plugin</artifactid> <version>1.0</version> <executions> <execution> <id>make-sonar</id> <phase>compile</phase> <goals> <goal>sonar</goal> </goals> </execution> </executions> ...

i'm new python, question might easy, anyway, patience: as trying call newton-raphson method calculate implied volatility in black-scholes formula call/put option pricing, first thing is, newton method in scipy.optimize seems calculate function's zeros, in black-scholes formula, want function's value option price, not zero. (i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...
