O nama<\/h4>\n

\nU 1C razvijamo ne samo platformu 1C: Poduze\u0107e<\/a><\/noindex> na C++<\/a><\/noindex> i JavaScript<\/a><\/noindex>, ve\u0107 i aplikacije na Javi \u2013 posebno novo razvojno okru\u017eenje Alati za razvoj poduze\u0107a<\/a><\/noindex> na bazi Eclipse, a server je duboko integriran s platformom messengera \u2013 Sistemi interakcije<\/a><\/noindex>.<\/p>\n

Uvod<\/h4>\n

\nKao sistem za gradnju Java aplikacija naj\u010de\u0161\u0107e koristimo maven, i u ovom kratkom \u010dlanku bismo \u017eeljeli govoriti o jednom od problema s kojim smo se suo\u010dili u procesu organizacije razvoja, i o pristupu koji je omogu\u0107io rje\u0161avanje tog problema.
\n<\/a><\/noindex><\/p>\n

Pretpostavke i radni proces<\/h4>\n

\nZbog specifi\u010dnosti razvoja u na\u0161im maven projektima koristimo relativno mnogo modula, ovisnosti i podprojekata. Broj pom datoteka u jednom stablu mo\u017ee se brojati u desecima, pa \u010dak i stotinama.<\/p>\n

\"Iskustvo
\n
\n\u010cinilo bi se: ni\u0161ta stra\u0161no, jednom stvoreno i zaboravljeno. Ako treba ne\u0161to promijeniti ili dodati u sve datoteke odjednom, postoji mno\u0161tvo prakti\u010dnih alata u urednicima i IDE-ima. A koja je naj\u010de\u0161\u0107a redovita promjena pom.xml? Smatramo da je to promjena verzija projekata i ovisnosti. Mogu\u0107e je da se netko s tim ne sla\u017ee, ali kod nas je situacija upravo takva. Razlog le\u017ei u tome \u0161to paralelno s jezgrom razvijamo mnogo vlastitih biblioteka, a za stalnu reproduktivnost rezultata gradnje i testiranja, kori\u0161tenje snaphotova nam se ne \u010dini prakti\u010dnim pristupom. Zbog toga moramo podizati broj verzije u projektima pri svakoj gradnji.<\/p>\n

Tako\u0111er, programer ponekad ima potrebu sastaviti svoju granu bilo koje biblioteke i provjeriti njenu funkcionalnost u svim ovisnostima, zbog \u010dega se u njima svima mora ru\u010dno mijenjati verzija.<\/p>\n

Prvotno rje\u0161enje<\/h4>\n

\nS tako \u010destim i vi\u0161estrukim promjenama verzija, proces unutar CI \u017eeli se pojednostaviti i automatizirati. Ovdje poma\u017ee prakti\u010dni i poznati plugin versions-maven-plugin<\/i> \u2014 povezujemo ga i pokre\u0107emo <\/p>\n

mvn -N versions:set -DnewVersion=2.0.1 <\/i><\/p>\n

i maven \u0107e u\u010diniti sve kako treba: pro\u0107i \u0107e kroz hijerarhiju od vrha do dna, sve verzije zamijeniti \u2014 ljepota! Sada je preostalo podi\u0107i pull-request, kolege \u0107e pregledati promjene, i brzo se mo\u017eemo uklju\u010diti u trunk. Brzo? Nije ba\u0161 tako. Par stotina pom.xml<\/i> u pregledu, a to ne uklju\u010duje kod. Osim toga, nitko nije imun na merge konflikte s tako velikim brojem promijenjenih datoteka. Ovde treba napomenuti da se tokom CI promene verzija automatski de\u0161avaju zajedno sa promenom funkcionalnosti, a ne odvojeno.<\/p>\n

Nove mogu\u0107nosti<\/h4>\n

\nNa neko vreme smo se smirili i, pomiriv\u0161i se, tako smo \u017eiveli, dok de\u010dki iz Maven Apache Project<\/a><\/noindex> nisu uklju\u010dili u maven, po\u010dev\u0161i od verzije 3.5.0-beta-1, podr\u0161ku za takozvane \"zamjenike\" verzija (placeholders). Su\u0161tina tih zamjenika je da pom.xml<\/i> umesto konkretnog navo\u0111enja verzije projekta koriste promenljive ${revision}<\/i>, ${sha1}<\/i> i ${changelist}<\/i>. Same vrednosti ovih svojstava se defini\u0161u ili u elementu <properties<\/i>>, ili ih mo\u017eemo definisati preko sistemskog svojstva<\/p>\n

mvn -Drevision=2.0.0 clean package<\/i><\/p>\n

Vrednosti sistemskih svojstava imaju prednost nad vrednostima definisanim u <properties<\/i>>.<\/p>\n

Surova stvarnost<\/h4>\n

\nSve je dobro i lepo, vreme je da osetite zadovoljstvo, ali ne. Ispostavlja se da ovaj na\u010din nije pogodan za install i deploy, jer u opisima artefakata koji se objavljuju u repozitorijumu ne\u0107e se zameniti ${revision}<\/i> na njenu vrednost i maven dalje ne\u0107e razumeti o \u010demu se uop\u0161te radi.<\/p>\n

Svetlost na kraju tunela<\/h4>\n

\nTreba potra\u017eiti re\u0161enje problema. Situaciju bi moglo spasiti flatten-maven-plugin<\/a><\/noindex>. Ovaj plugin omogu\u0107ava sve varijable u pom, ali tako\u0111er izbacuje mno\u0161tvo drugih informacija koje su potrebne samo prilikom izgradnje i nisu potrebne prilikom uvoza objavljenih artefakata u druge projekte. Tako\u0111er, plugin \"izravnava\" sve parent-child ovisnosti, i na kraju se dobivaju ravni pom-ovi koji uklju\u010duju sve \u0161to je potrebno. Neugodnost je bila u tome \u0161to izbacuje \"suvi\u0161no\" previ\u0161e, \u0161to nas je potpuno smetalo. Nakon prou\u010davanja informacija o razvoju ovog plugina, ispostavilo se da nismo jedini u ovoj situaciji, te je ve\u0107 u kolovozu 2018. na GitHubu u repozitoriju plugina stvoren pull-request s \u017eeljom da se omogu\u0107i samostalno odre\u0111ivanje kako \"pokvariti\" pom.xml. Razvija\u010di su poslu\u0161ali glasove onih kojima je to trebalo, i ve\u0107 u prosincu, s izlaskom nove verzije 1.1.0, u flatten-maven-plugin uveden je novi na\u010din resolveCiFriendliesOnly, koji je bio savr\u0161eno prilago\u0111en \u2013 ostavlja pom.xml takvim kakav jest, osim elementa <version><\/i> i omogu\u0107ava ${revision}<\/i>, ${sha1}<\/i> i ${changelist}<\/i>.<\/p>\n

Sretan zavr\u0161etak<\/h4>\n

\nOd sada, da bismo promijenili verziju \u010ditavog projekta i obavijestili sve ovisnosti, potrebno je samo urediti element <revision<\/i>> u samo jednom korijenskom pom.xml<\/i>. Na recenziju sti\u017ee ne stotinu-dvije ovih datoteka s istom izmjenom, ve\u0107 jedna. Tako\u0111er, otpaodstava potreba za kori\u0161tenjem versions-maven-plugin<\/i>.
