以下代码使用 Maven 元数据创建一个 war 文件。问题是，当没有任何变化时，我在重建时看不到尽可能多的 UP-TO-DATE 消息。显然我的任务输入/输出有问题。问题是我可以在没有任何实际代码更改的情况下看到依赖项如何更改。当实际上没有任何代码需要重建时，这将导致 Maven 元数据发生变化。不知道如何处理。请注意，我们的 Jar 具有相同的格式，这意味着我也必须修复它们。

我看到的例子：

...
:redacted:redacted-redacted:com-redacted:processResources UP-TO-DATE
:redacted:redacted-redacted:com-redacted:classes
:redacted:redacted-redacted:com-redacted:generatePomFileForMavenJavaPublication
:redacted:redacted-redacted:com-redacted:jar
:redacted:redacted-redacted:redacted:compileJava
:redacted:redacted-redacted:redacted:processResources UP-TO-DATE
:redacted:redacted-redacted:redacted:classes
:redacted:redacted-redacted:redacted:generatePomFileForMavenJavaPublication
:redacted:redacted-redacted:redacted:jar
:redacted:redacted-redacted:com-redacted:compileJava

有问题的 Gradle 代码：

apply plugin: 'war'
apply plugin: 'maven-publish'

publishing {
    publications {
        mavenJava(MavenPublication) {
            from components.java
        }
    }
}

publishing {
    repositories {
        maven {
            url "$buildDir/fauxMvnRepo"
        }
    }
}

war {

    def pomGenerationTask = project.tasks.findByName('generatePomFileForMavenJavaPublication')

    if (pomGenerationTask) {
        dependsOn 'generatePomFileForMavenJavaPublication'
        pomGenerationTask.doLast {
            createPropertiesFile()
        }

    } else {
        project.tasks.whenTaskAdded { addedTask ->
            if (addedTask.name == 'generatePomFileForMavenJavaPublication') {
                project.tasks.war.dependsOn 'generatePomFileForMavenJavaPublication'
                addedTask.doLast {
                    createPropertiesFile()
                }
            }
        }
    }

    into("META-INF/maven/$project.group/$project.archivesBaseName") {
        from new File(project.buildDir, 'publications/mavenJava')
        rename "pom-default.xml", "pom.xml"

    }

    manifest {
        attributes('Implementation-Title': project.name,
                'Implementation-Version': project.version,
                'Archiver-Version': "Gradle ${name} task",
                'Built-By': System.getProperty('user.name'),
                'Built-JDK': System.getProperty('java.version'),
                'Created-By': "Gradle",
                'Source-Compatibility': project.sourceCompatibility,
                'Target-Compatibility': project.targetCompatibility,
                'Implementation-Vendor-Id': "com.funkyChicken"
        )
    }

    doLast {
        copy {
            from destinationDir.absolutePath + File.separator + "$archiveName"
            into destinationDir
            rename { String fileName ->
                fileName.replace("${archiveName}", "${baseName}.${extension}")
            }
        }
    }
}

def createPropertiesFile() {
    File propsFile = new File("$buildDir/publications/mavenJava/pom.properties")

    def props = new Properties()
    propsFile.createNewFile()

    props.setProperty("version","$version")
    props.setProperty("groupId","$project.group")
    props.setProperty("artifactId","$project.archivesBaseName")

    props.store(propsFile.newWriter(), "#Generated by Gradle")
}
