eclipse - What's the fastest way to get all build errors in a Java project? -

-

currently i'm looking @ integrating build processes source control (git hooks specifically). i'm trying write pre-commit hook checks build errors in java project (a medium-large test development project) , fails allow commits contain errors in build. turning out rather challenging.

the approach here uses command-line eclipse tool build , output warnings , errors. technically work, it's slow , may cause problems eclipse ide (i've had heap allocation errors). i've looked @ solutions using ant these approaches don't seem simple one-line solution, , may still slow.

my main question: what's fastest (run-time compilation speed) way build , validate java project, command line? i'd solution returns 0 no errors , else if errors present, i'm willing @ other things.

let's start basics:

  • pre-commit hooks run on server , not client. there no working directory default. have make sure javac available, , correct version.
  • your pre-commit hook freeze up user's terminal until completion.

now, how long take checkout fresh copy of java project, run ant, wait compile, , process output of compile? minute or two? 20 seconds? 10 seconds? 10 seconds feel forever wait git push complete. and, if other users want commit code, have wait.

a better, , easier approach use continuous build server jenkins. jenkins easy setup. (it comes own application server built in) , has hundreds of plugins can use report health of project. if compile cannot happen, jenkins email culprit , whomever else mention.

we have our jenkins setup ant builds, maven builds, , use either git or subversion our repository (depending upon project). jenkins builds project, keeps console log, , fail build if build.xml fails. @ our place, means start pestering developer fix problem or undo changes. @ last workplace, developers given 10 minutes fix build, or undo changes.

not can jenkins let know when build fails, has plugins can report on java compiler warnings, javadoc warnings, run findbugs, pmd, find duplicate lines of code (via cpd comes pmd), , report in series of graphs. can mark builds unstable (build completes, problematic) or fail build based upon number of issues found these tools.

jenkins can run unit tests, , again graph results, run coverage analysis jacoco or cobertura or emma.

so, take @ jenkins. it's easy setup , want , more.

java - Copying object fields -

-
what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
