java - 在多项目 gradle 构建中，如何将 subproject-A.war 的内容打包到 subproject-B.jar

Question

问题:给定以下多项目gradle构建

superproject
    subproject-A -> war
    subproject-B -> jar

我正在寻找一种方法来配置 subproject-B 以解压缩由 subproject-A 生成的 war 的内容并拥有解压缩的 webapp 目录的内容(包含用于部署到容器中的类和资源)在根级别与类一起打包到 subproject-B 的应用程序分发中，后者的资源和依赖关系。因此，为 subproject-B 生成的分发结构应该如下所示:

subproject-B-0.1.0
    bin/...
    lib/
        META-INF/ (<-- from B)
        WEB-INF/  (<-- from A.war)
        css/      (<-- from A.war)
        js/       (<-- from A.war)
        *.jar     (code and dependencies of B)

将资源从 A 复制到 B 的问题已得到解答 here .在这里，我需要复制一个动态生成的构建工件的内容(通常将其复制到 main/resources 中就可以了，因为后者将被打包到 jar 中).

基本原理 subproject-B 是一个独立的 Java 应用程序，运行 tomcat-embed-server 和 JavaFX WebView 在 localhost 上访问 subproject-B 的网络应用程序，将其他网络应用程序变成一种独立的桌面应用程序。这 20 行代码在 Eclipse 中运行良好，但似乎对分发打包提出了挑战。

我终于找到了一个解决方案，所以为了那些面临类似问题的人的利益将其张贴在这里:

subprojectA/build.gradle

apply plugin: "java"
apply plugin: "war"

archivesBaseName = "subprojectA"

sourceCompatibility = 1.8
compileJava.options.encoding = "utf-8"

war {
    manifest {
        archiveName = "$baseName.$extension"
        attributes "Implementation-Title": archivesBaseName, 
                   "Implementation-Version": version
    }
}

// declare configuration to refer to in superprojectB
configurations {
    subprojectAwar
}
// make this configuration deliver the generated war
dependencies {
    subprojectAwar files(war.archivePath)
}

subprojectB/build.gradle

apply plugin: "java"
apply plugin: 'application'

archivesBaseName = "subprojectB"

sourceCompatibility = 1.8
compileJava.options.encoding = "utf-8"

// declare configuration to take files from
configurations {
    subprojectAwar
}

dependencies {
    // bind the configuration to the respective configuration in subprojectA
    subprojectAwar project(path: ":subprojectA", configuration: "subprojectAwar")

    compile "org.apache.tomcat.embed:tomcat-embed-core:$tomcatEmbedVersion"
    compile "org.apache.tomcat.embed:tomcat-embed-websocket:$tomcatEmbedVersion"
    compile "org.apache.tomcat.embed:tomcat-embed-logging-log4j:$tomcatEmbedVersion"
    compile "org.apache.tomcat.embed:tomcat-embed-jasper:$tomcatEmbedVersion"
}

mainClassName = 'org.project.subprojectB.StartServer'

jar {
    // make sure this project is assembled after the war is generated
    dependsOn(":subprojectA:assemble")

    manifest {
        archiveName = "$baseName.$extension"
        attributes "Implementation-Title": archivesBaseName,
                   "Implementation-Version": version
        attributes 'Main-Class': '$mainClassName'
    }
    // if you need to copy the content of the war into the jar:
    // (otherwise only to the distribution, see below)
    /*
    from(zipTree(configurations.subprojectAwar.collect { it }[0])) {
        into ""
        exclude '**/META-INF/**'
    }
    */
}

// copy the content of the war excluding META-INF into the lib of superprojectB
applicationDistribution.from(zipTree(configurations.subprojectAwar.collect { it }[0])) {
     into "lib"
     exclude '**/META-INF/**'
}
