如何使用Gradle更新现有的war/jar/zip文件？

Question

我需要制作一个现有war文件的副本，并更新其中的一个xml文件。我对如何做到这一点的想法是：

• 从现有WAR中提取文件
• 替换文件中的字符串
• 复制警告
• 将修改的文件添加回复制的WAR

task updateWar() << {
    def originalWar = file("deploy/mywar.war")
    def outputDir = file("deploy")
    def wars = [ "war1", "war2" ]
    wars.each() { warFile ->        
        delete "deploy/WEB-INF/ejb.xml"
        copy {
            //Step 1
            from(zipTree(originalWar)) {
                include 'WEB-INF/ejb.xml'
            }
            into outputDir
            //Step 2
            filter{
                String line -> line.replaceAll("<value>OriginalText</value>",
                        "<value>UpdatedText</value>")
            }
        }
        //Step 3
        copy {
            from outputDir
            into outputDir
            include 'mywar.war'
            rename 'mywar.war',"${warFile}.war"
        }       
        //Step 4
        ant.jar(update: "true", destfile: deploy/${warFile}.war") {
            fileset(dir: deploy", includes: 'WEB-INF/**')
        }
    }
}

task updateWar(type: Zip) {
    def originalWar = file("deploy/mywar.war")
    def outputDir = file("deploy")
    archiveName = "war2.war"
    destinationDir = outputDir
    from (zipTree(originalWar),{
        filesMatching("WEB-INF/ejb.xml") {
            filter{
                String line -> line.replaceAll("<value>OriginalText</value>",
                        "<value>UpdatedText</value>")
            }
        }
    })
}

假设您只想用res文件夹中的文件替换war中的原始文件，下面是如何实现的：

task updateWar(type: Zip) {
    def originalWar = file("deploy/mywar.war")

    archiveBaseName = 'mywar'
    archiveExtension = 'war'

    from(zipTree(originalWar)) {
        // Remove the original ejb.xml if it exists
        exclude("**/WEB-INF/ejb.xml")
    }

    // Include our own ejb.xml
    from('res/ejb.xml') {
        into('WEB-INF/')
    }
}
