dependency injection - Java method with @Inject annotation: False-positive for the rule "Unused "private" methods should be removed"? -

-

we using java 8 , dependency injection (guice). have false-positive sonar issue, unused method, although method invoked via reflection guice injector, due inject annotation.

affected code:

 @inject  private void settransactionalcommandstack(transactionalcommandstack transactionalcommandstack) {    ... }

sq reports violation of rule squid:unusedprivatemethod

unused "private" methods should removed

at place , says

private method 'settransactionalcommandstack' never used

.

the eclipse environment has check unused methods detects correctly , puts warning if have no @inject annotation method. same expect in sonarqube.

i tested both annotation javax.inject.inject , com.google.inject.inject. in both cases sonarqube reports method unused.

sq version: 5.3

java plugin version: 3.14

this issue has been fixed in version 4.0 of java analyzer, compatible sq lts 5.6. see corresponding jira ticket sonarjava-1179

i using volley upload list of images server. happens within service. once image uploaded remove list. problem arises when internet connection breaks. when internet connection breaks , comes again thinking of adding images yet uploaded request queue. this can result in more 1 copy of same image saved on server request same image might have gone through before getting rseponse. how can address scenario? i'm not quite sure why you're using service schedule requests volley automatically runs it's request in seperate thread. nevertheless can listen both request results, successful , unsuccessful adding listeners. you can remove image list schedule request using volley. if succeeds can carry on desired, if fails can add again list. public static request getimageuploadrequest(final string image) { response.listener<t> responselistener = new response.listener<t>() { @override public void onresponse(t response
