java - Checking out a Git repository by branch or commit ID using JGit -


i cloning repositories jgit using following:

git.clonerepository()     .seturi(uri)     .setdirectory(createtempdir())     .setbranchestoclone(singleton("refs/heads/" + branch))     .setbranch("refs/heads/" + branch)     .call();

however allow branch commit id. how implement this?

while cloning git repository, can specify branches (or more references) cloned. not specific jgit applies cli git.

a remote repository can queried available references along commit ids, arbitrary commit id cannot cloned.

with jgit, lsremotecommand can used obtain available references without downloading respective history. or can specify pre-known reference clonecommand in order clone given reference along history.

if performance , bandwidth aren't issue, could, of course, clone repository references (clonecommand.setcloneallbranches( true )) , once available locally, check out desired commit.

transpose - Maple isnt executing function but prints function term -

im using maple im in worksheetmode tried using maple input , 2d input , want transpose matrix a: := `<|>`(`<,>`(1, .5, -2), `<,>`(.5, 9/4+b, 5+3*b), `<,>`(-2, 5+3*b, 18+9*b+4*a)); b:= transpose(a); when exectute sheet dont translated values, there same input. matrix looks same input matrix plus function term. you can see picture in following link: why arent functions executed? meanwhile b:=a^+ doing right way , transposed matrix. other functions return function body instead needed values... if using 2d input mode (the default) space you've got between transpose , bracketed (b) interpreted multiplcation. rid of such space. also, either load package @ start of document like, with(linearalgebra): before calling transpose command package, or call it's full name like, linearalgebra:-transpose(b);
