How can I force the writing of a manifest in a jar?

Hello,

I’m in the process of moving a big ant project to gradle. So far here is the build.gradle that I got :

allprojects {
    apply plugin: 'java'
          repositories {
            mavenCentral()
        }
  }
  apply plugin: 'checkstyle'
apply plugin: 'application'
apply plugin: 'eclipse'
apply plugin: 'idea'
  dependencies {
    compile 'log4j:log4j:1.2.16'
    compile 'de.sciss:jsyntaxpane:1.0.0'
    compile 'org.jdom:jdom:1.1'
}
  configurations {
    // custom config of files we want to include in our jar
    includeInJar
}
  mainClassName = "org.contikios.cooja.Cooja"
libsDirName = '../dist'
  manifest
{
 attributes 'Main-Class': "org.contikios.cooja.Cooja"}
      sourceSets {
    main {
        java {
            srcDirs = ["java"]
        }
        resources {
            srcDirs = ["config/"]
        }
    }
}
  run {
    println workingDir
    // fork="yes"
    maxHeapSize "512m"
        main = "org.contikios.cooja.Cooja"
    workingDir = "build"
}
  task run_64(dependsOn: jar, type: JavaExec) {
    description = "Will run the cooja simulator for 64 architecture"
        // fork: yes
        main = "org.contikios.cooja.Cooja"
        maxHeapSize = "512m"
        systemProperty "user.language", "en"
        //jvmArgs "-d64", "-XX:+ShowMessageBoxOnError"
}
  task run_errorbox(dependsOn: jar, type: JavaExec) {
    // fork: yes
    main = "org.contikios.cooja.Cooja"
    maxHeapSize = "512m"
    systemProperty "user.language", "en"
    //
  <java fork="yes" dir="${build}">
    //
    <jvmarg value="-XX:+ShowMessageBoxOnError"/>
    //
    <env key="LD_LIBRARY_PATH" value="."/>
    //
  </java>
}
  task runprof(dependsOn: jar, type: JavaExec) {
    // fork: yes
    main = "org.contikios.cooja.Cooja"
    jvmArgs "-agentlib:yjpagent"
}
  task runfree(dependsOn: jar, type: JavaExec) {
    // fork: yes
    main = "org.contikios.cooja.Cooja"
    maxHeapSize = "1536m"
    // <arg line="${args}"/>
}
  task run_bigmem(dependsOn: jar, type: JavaExec) {
    // fork: yes
    main = "org.contikios.cooja.Cooja"
    maxHeapSize = "1536m"
}
  task run_nogui(dependsOn: jar, type: JavaExec) {
    // fork: yes
    // <arg line="-nogui=${args}"/>
    main = "org.contikios.cooja.Cooja"
        maxHeapSize = "512m"
}
  task run_applet(dependsOn: jar, type: JavaExec) {
    //
  <exec executable="appletviewer" dir="${build}">
    //
    <arg value="-J-Djava.security.policy=cooja.policy"/>
    //
    <arg value="cooja.html"/>
    //
    <env key="CLASSPATH" path="${build}"/>
    //
  </exec>
}
  task export_jar(dependsOn: jar, type: JavaExec) {
    // fork: yes
    maxHeapSize "512m"
    main "org.contikios.cooja.util.ExecuteJAR"
        //
      <arg file="${CSC}"/>
        //
      <arg file="exported.jar"/>
}

I can build my JAR just fine with that. The problem is that I can’t launch the jar that I’ve created with a command like : java -jar cooja.jar because I get the following error : aucun attribut manifest principal dans cooja.jar

What did I do wrong. The project is quite old and I’m quite new to gradle :wink: Feel free to tell me all the mistakes I did :slight_smile:

‘manifest { … }’ nees to go inside ‘jar { … }’.

Thanks :slight_smile: Do you see other rookie mistakes in my build.gradle?
