File duplicati nel file .war creato da Gradle

Question

Ho riscontrato un problema con i file duplicati con il mio script di compilazione Gradle.

La mia struttura di directory è lo standard Maven, oltre ad alcuni indici aggiuntivi per varie configurazioni di build:

/src/main/java 
/src/main/resources 
/src/main/dev/resources 
/src/main/prod/resources 

I file da /src/main/resources e /src/main/dev/resources sono apparentemente gestite sia compito processResources e la war, e finiscono in il file .war due volte. Come posso evitare che ciò accada senza escludere manualmente ogni singolo file nella configurazione di guerra?

Il mio intero build.gradle è incluso di seguito; nota buildEnvironment è impostata su dev per impostazione predefinita, ma potrebbe anche essere prod.

Answer 1

non ho ancora testato la configurazione qui, ma credo che sia perché si sta aggiungendo main.resources.srcDirs += "src/main/$buildEnvironment/resources" a sourceSets. Con l'aggiunta di questo che hai ora i seguenti sourceSets se buildEnvironment = 'dev':

• src/main/java
• src/main/resources
• src/main/dev/risorse

Questo significa che se avete una risorsa chiamata myfile.txt sia src/main/resources e src/main/dev/resources si dovrebbe ottenere i seguenti file:

• WEB-INF/classes/Myfile.txt
• WEB-INF/classes/dev/MyFile.txt

Per risolvere questo problema si può solo muovere le risorse dev/prod al di fuori di src/main, es. in questo modo:

• src/main/java
• src/main/risorse
• src/dev/risorse
• src/prod/risorse

e utilizzare i seguenti sourceSet invece :

main.resources.srcDirs += "src/$buildEnvironment/resources" 

Poi tutte le risorse dev/prod sovrascriverà la res in src/main/resources.
