android - Proguard warnings "can't write resource [META-INF/MANIFEST.MF] (Duplicate zip entry)" -


i'm using intellij , running proguard in debug mode can't seem rid of warnings such as:

proguard: [myapplication] warning: can't write resource [meta-inf/manifest.mf]  (duplicate zip entry [android-support-v13.jar:meta-inf/manifest.mf])

this project has couple of modules , android-support-v13.jar being used on 2 of them. thought issue removed library libs folder, added project library , added dependency both modules. didn't solve anything, warning persists , don't understand why.

i know these warnings don't affect clean build happy build!

possibly 'proguard.cfg' problem. include '-injars'? if project includes project library, jars can processed twice. post 'proguard.cfg'?

extract http://proguard.sourceforge.net/index.html#manual/troubleshooting.html:

your input jars contain multiple resource files same name. proguard continues copying resource files usual, skipping files used names. once more, warning may indication of problem though, it's advisable remove duplicates. convenient way specifying filters on input jars. there no option switch off these warnings.

option #1:

as can't post '-injars', check if include either 'android-support-v13.jar' or library included in project includes 'android-support-v13.jar'.

assuming building ant inside intellij idea, mustn't add -injars, -outjars, or -libraryjars options; ant script you.

option #2:

although warnings harmless, clean build happy build, try:

and

https://gist.github.com/paulpv/4439012

option #3:

include (!meta-inf/manifest.mf) after each '-injars' command 

-injars library.jar(!meta-inf/manifest.mf)

option #4: android proguard duplicate definition

fixed moving 3rd party libraries directory, in case 'lib'. added

-injars lib/jmdns.jar

to proguard.cfg file.

option #5: android - proguard duplicate zip entry error

if proguard config file includes following line, remove it:

-injars bin/classes

option #6: android obfuscate app using proguard keeps obfuscating library jars - or it?

i found way make proguard leave library jars alone ask preserve package names, eg:

-keep class javax.** { *; } -keep class org.** { *; } -keep class twitter4j.** { *; }

option #7:

a weird solution (deleting meta-inf folder in src folder) similar here.

the documentation of error mentioned in title says if commands out of sync; can't run command now in client code, calling client functions in wrong order. this can happen, example, if using mysql_use_result() , try execute new query before have called mysql_free_result(). can happen if try execute 2 queries return data without calling mysql_use_result() or mysql_store_result() in between. from here: http://dev.mysql.com/doc/refman/5.0/en/commands-out-of-sync.html but in first query not fetching data mysql database, inserting. , in second query getting data database. here code $connection = mysqli_connect("localhost","username","password","tbl_msgs"); if(mysqli_connect_errno($connection)) { die("failed connect mysql: " . mysqli_connect_error()); } $query = "insert users (total_comments, total_views) values ({$total_comments}, {$total_views});"; $query .= "insert msgs (no...

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).

i'm using named queries fetch entities database using jpa , hibernate , came across puzzling me: how come there no default implementations of javax.persistence.parameter interface? i rather impressed how @staticmetamodel used criteriabuilder in jpa2 meaning type safety , don't have mess around setting string names. wanted apply similar of jpa1 ejb's i'm working on: dealergroup_.class: public dealergroup_ { public parameter<integer> id = new parameterimpl<integer>("id"); /// etc... } dealergroupfacade.class: // ... public dealergroup fetch(integer id) { typedquery<dealergroup> query = em.createnamedquery("dealergroup.fetchbyid", dealergroup.class); query.setparameter(dealergroup_.id, query); return query.getsingleresult(); } // ... i surprised find there no implementations of parameter interface - of course, implement myself absence makes me suspicious may mistake using in way? should implementing parameter...
