gradle - could not find method compile() for arguments

Question

I'm trying to execute some .sql scripts and then deploy web app using gradle tomcat plugin.

But when I make any attempt to run gradle I've got an error

My buildscript looks like this

buildscript {
//repository location
repositories {
    mavenCentral()
    jcenter()
}
//dependencies
//did not divide them into runtime&compile
dependencies {
    //aspectJ dependencies
    compile 'org.aspectj:aspectjlib:1.6.2'
    compile 'org.aspectj:aspectjrt:1.7.4'
    compile 'org.aspectj:aspectjweaver:1.7.4'
    //servlet
    compile 'javax.servlet:javax.servlet-api:3.0.1'
    //jdbc postresql
    compile 'org.postgresql:postgresql:9.2-1004-jdbc4'
    //commons dbcp
    compile 'commons-dbcp:commons-dbcp:1.2.2' 
    //spring & spring MVC dependencies
    compile 'org.springframework:spring-core:' + spring_version
    compile 'org.springframework:spring-web:' + spring_version
    compile 'org.springframework:spring-webmvc:' + spring_version
    compile 'org.springframework:spring-jdbc:' + spring_version
    compile 'org.springframework:spring-aspects:' + spring_version
    //spring security
    compile 'org.springframework.security:spring-security-core:' + spring_security_version
    compile 'org.springframework.security:spring-security-web:' + spring_security_version
    compile 'org.springframework.security:spring-security-config:' + spring_security_version
    //JSTL
    compile 'jstl:jstl:1.2'
    //slf4j-log4j
    compile 'org.slf4j:slf4j-api:1.7.0'
    compile 'org.slf4j:slf4j-log4j12:1.7.0'
    compile 'log4j:log4j:1.2.17'
    //mybatis
    compile 'org.mybatis:mybatis:3.2.4'
    compile 'org.mybatis:mybatis-spring:1.2.2'
    //gson
    compile 'com.google.code.gson:gson:2.2.4'
    //validation jsr303
    compile 'javax.validation:validation-api:1.0.0.GA'
    //junit4(test?)
    compile 'junit:junit:4.11'
    //spring test(test?)
    compile 'org.springframework:spring-test:' + spring_version
    //java mail
    compile 'javax.mail:mail:1.4'

    //tomcat plugin
    def tomcatVersion = '7.0.53'
    tomcat "org.apache.tomcat.embed:tomcat-embed-core:${tomcatVersion}",
        "org.apache.tomcat.embed:tomcat-embed-logging-juli:${tomcatVersion}"
    tomcat("org.apache.tomcat.embed:tomcat-embed-jasper:${tomcatVersion}") {
        exclude group: 'org.eclipse.jdt.core.compiler', module: 'ecj'
    }

    //additional classpath
    classpath 'org.gradle.api.plugins:gradle-tomcat-plugin:1.2.3'
    classpath 'org.postgresql:postgresql:9.2-1004-jdbc4'
}
}

In build.gradle there are also several tasks and several apply plugin.

What's the problem? Full stack trace

My build.gradle is in a project folder.

Answer 1

The build script is mixing up buildscript dependencies (i.e.

1. dependencies of the build itself; typically this means Gradle plugins
2. with regular dependencies (i.e. dependencies of the code to be compiled/run).

2 needs to go into dependencies { ... }, not into buildscript { dependencies { ... } }.

Everything but the classpath dependencies are regular dependencies.
