Określ środowisko "PATH" nie działa podczas uruchamiania programu Gradle 'exec'

Question

Próbowałem wywołać npm w mojej kompilacji Gradle. Urządzenie npm jest instalowane za pośrednictwem homebrew w /usr/local/bin. Gradle nie uda się znaleźć npm podczas jego wykonywania.

Jednak zawsze kończyło się niepowodzeniem po dodaniu zmiennej środowiskowej PATH podczas wykonywania komendy npm.

Jedynym sposobem obejścia tego problemu jest użycie bezwzględnej ścieżki dla npm, nie ma sensu używanie tego samego skryptu gradle w systemie Linux.

Czy ktoś miał podobny problem? Czy powinienem otworzyć bilet na gradle?

Poniżej jest moje build.gradle,

import org.gradle.api.tasks.Exec 
import org.apache.tools.ant.taskdefs.condition.Os 

ext { 
     npmCommand = Os.isFamily(Os.FAMILY_WINDOWS) ? 'npm.cmd' : 'npm' 
     npmPath = Os.isFamily(Os.FAMILY_WINDOWS) ? '' : '/bin/:/usr/bin/:/usr/local/bin/' 
} 

task wrapper(type: Wrapper) { 
    gradleVersion = '2.4' 
} 
// Install packages from package.json 
task npm(type: Exec) { 
     description = "Grab NodeJS dependencies (from package.json)" 
     environment PATH: npmPath 
     workingDir = 'src/webapp' 
     commandLine = [npmCommand, "install"] 
     inputs.file "src/webapp/package.json" 
} 

Poniżej jest kompletna wyjście Gradle,

./gradlew npm -S 
:npm FAILED

Zadanie będzie działać dobrze, jeśli zmiana na ścieżkę bezwzględną KMP,

npmCommand = Os.isFamily(Os.FAMILY_WINDOWS) ? 'npm.cmd' : '/usr/local/bin/npm'

Answer 1

Wystąpił błąd, gdy katalog src/webapp nie istniał w katalogu głównym katalogu.

skończyło się tylko następujące:

task npm(type: Exec) { 
     description "Grab NodeJS dependencies (from package.json)" 
     workingDir 'src/webapp' 
     commandLine npmCommand, "install" 
     doLast { 
      def d1 = project.file('src/webapp') 
      println "d1: $d1, ${d1.exists()}" 
     } 
} 

bez konieczności ustalania środowiska, tak długo, jak src/webapp reż został stworzony. Nie wiem, co robi twoja wartość inputs.file, npm szuka src/webapp/package.json z powodu ustawienia workingDir w zadaniu, więc usunąłem go.

Dodatkowo nie potrzebujesz importu do Exec.

Jeśli dodasz dane wyjściowe ./gradlew npm -S do swojego pytania, porównasz je z moim błędem i zobaczę, czy mogę pomóc dalej.

EDYCJA: Dodałem do bloku ostatni blok. Powinien znaleźć katalog src/webapp i wydrukować jego lokalizację i "true", jeśli istnieje, gdy katalog jest obecny podczas wykonywania zadania. Co mówi wynik?

Answer 2

Miałem ten sam problem po aktualizacji systemu operacyjnego. Dla mnie poprawka polegała na sprawdzeniu mojej zmiennej PATH i zatrzymaniu demona gradle. Następnie demon ponownie ocenia ścieżkę. Np .:

gradle --stop 
gradle npm 

Answer 3

Wystarczy zmienić do tego

ext { 
    npmCommand = Os.isFamily(Os.FAMILY_WINDOWS) ? 'npm.cmd' : '/usr/local/bin/npm' 
    npmPath = Os.isFamily(Os.FAMILY_WINDOWS) ? '' : '/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin' 
}
