ubuntu - Maven error: Could not find or load main class .usr.share.maven.boot.plexus-classworlds-2.x.jar -


i have upgraded ubuntu 14.04 16.04 , started getting following error when running mvn commands (version 3.3.9): error: not find or load main class .usr.share.maven.boot.plexus-classworlds-2.x.jar. environment variables declared follows:

$java_home: /usr/lib/jvm/java-8-oracle $path: /usr/local/texlive/2015/bin/x86_64-linux:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin $m2_home: /usr/share/maven $m2: /usr/share/maven/bin

when trying find solution, i've tried removing m2 , m2_home variables suggested on various threads, resulted in getting different error: error: not find or load main class org.codehaus.plexus.classworlds.launcher.launcher. have tried running apt-get remove --purge maven , installing again downloading .tar.gz archive, in both cases, nothing has changed.

when looking /usr/share/maven/boot folder, there chain of symlinks pointing plexus-classworlds-2.x.jar -> /usr/share/java/plexus-classworlds2-2.5.2.jar. missing dependencies? or there old configuration files did not removed --purge?

edit: when execute mvn root, launcher error instead of plexus-classworlds-2.x. also, have removed , reinstalled plexus libraries, yet no change.

check if /usr/share/maven/boot has multiple jars pattern /usr/share/maven/boot/plexus-classworlds-*.jar.

mine like:

drwxr-xr-x 2 root root  4096 dec  23 14:21 ./ drwxr-xr-x 6 root root  4096 nov  14  2015 ../ -rw-r--r-- 1 root root 52684 dec  12  2015 plexus-classworlds-2.5.2.jar lrwxrwxrwx 1 root root    34 dec  10  2015 plexus-classworlds-2.x.jar -> ../../java/plexus-classworlds2.jar

this messes /usr/share/maven/bin/mvn bash script , executes wrong java command.

i had remove jar , leave symbolic link.

unity3d - Rotate an object to face an opposite direction -

i have object , b. when click on object b, rotates object b (a faces b). b doesn't face a. need following : when faces b, need face opposite direction. have code rotating @ b. how rotate face opposite direction after that? vector3 targetdirection = target - transform.position; float step = speed * time.deltatime; vector3 newdirection = vector3.rotatetowards (turretdome.transform.forward, targetdirection, step, 0.0f); turretdome.transform.rotation = quaternion.lookrotation (newdirection); you object facing object b, want inverse direction of object after that? objecta.transform.rotation = quaternion.inverse(objecta.transform.rotation) but lets assume example turretdome object a, (negate direction): turretdome.transform.rotation = quaternion.lookrotation (-newdirection); naturally, both of these snippets not show how smoothen rotation, seem know how use time.deltatime. just incase unsure, quaternion.lerp this

angular - Is it possible to get native element for formControl? -

i've got angular2 reactive form . created formcontrol s , assigned input fields by [formcontrol]=... . understand creates nativeelement <-> formcontrol link. my question: possible nativeelement formcontrol ? wanna myformcontrol.nativeelement.focus() i can share 1 terrible solution works me. in reactive forms can use either 1) formcontroldirective ts mycontrol = new formcontrol('') template <input type="text" [formcontrol]="mycontrol"> or 2) formcontrolname ts myform: formgroup; constructor(private fb: formbuilder) {} ngoninit() { this.myform = this.fb.group({ foo: '' }); } template <form [formgroup]="myform"> <input type="text" formcontrolname="foo"> </form> so these directives write patch like 1) formcontroldirective const originformcontrolngonchanges = formcontroldirective.prototype.ngonchanges; formcontroldirective.proto
