Gradle-Java项目的多重依赖

Question

Just started tying to use gradle, but not getting far. Please help.

I've followed the documentation, but it only show single dependencies or dependencies that I can't get to work. Here is my build.gradle file:

apply plugin: 'java'
sourceCompatibility = 1.7
OFFICEDB_VERSION = 'JAN12R2'

repositories {
    mavenCentral()
}

dependencies {
    compile group:
            'org.hibernate:hibernate-validator:5.0.0.Alpha1',
            'javax.validation:validation-api:1.1.0.Alpha1',
            'com.exlogs.officedb:common:${OFFICEDB_VERSION}',
            'com.exlogs.officedb:officedb-service:${OFFICEDB_VERSION}',
            'com.exlogs:eventhub:1.0.0-RC1',
            'commons-httpclient:commons-httpclient:3.1'

testCompile group: 'junit', name: 'junit', version: '4.+'
}

The problem is when I type in gradle build on the command line I get:

FAILURE: Build failed with an exception.

* Where:
Build file 'C:\Dev\Code\officedb\manpower\build.gradle' line: 10

* What went wrong:
A problem occurred evaluating root project 'manpower'.
> Could not create a dependency using notation: {group=org.hibernate:hibernate-validator:5.0.0.Alpha1}

But looking at the documentation this should be fine. Also all the example build files I've found are rather small or only have a single dependency. Does anyone have any views about using gradle for large commercial projects.

Thanks Adam

You need to specify configuration (similar to Maven scope, ie compile , testCompile , etc) for each dependency:

dependencies {
    compile 'org.hibernate:hibernate-validator:5.0.0.Alpha1'
    compile 'javax.validation:validation-api:1.1.0.Alpha1'
    compile "com.exlogs.officedb:common:${OFFICEDB_VERSION}"
    compile "com.exlogs.officedb:officedb-service:${OFFICEDB_VERSION}"
    compile 'com.exlogs:eventhub:1.0.0-RC1'
    compile 'commons-httpclient:commons-httpclient:3.1'

    testCompile group: 'junit', name: 'junit', version: '4.+'
    testCompile 'org.mockito:mockito-all:1.9.0'
}

group is a part of alternative syntax to provide dependency coordinates ( group: 'junit', name: 'junit', version: '4.+' ), not a special keyword.

Also note that you need double quotes to use variables in strings:

compile "com.exlogs.officedb:common:${OFFICEDB_VERSION}"
