gradle publish为什么运行最后一个任务

下面是相关的build.gradle代码段

version = '0.0.25-SNAPSHOT'
publishing {
    repositories {
        mavenLocal()
    }

    publications {
        maven(MavenPublication) {
            groupId = group
            artifactId = 'xyz-abc'
            version = version
            from components.java
        }
    }
}

task incrementSnapshotVersion {
    String jVersion = version
    int snapshotSuffixBegin = jVersion.lastIndexOf('-')
    String currentMinor = jVersion.substring(jVersion.lastIndexOf('.') + 1, snapshotSuffixBegin)
    String updatedMinor = (Integer.parseInt(currentMinor) + 1).toString()
    String major = jVersion.substring(0, jVersion.lastIndexOf(currentMinor))
    String newVersion = major + updatedMinor + "-SNAPSHOT"
    String s = buildFile.getText().replaceFirst("version = '$jVersion'", "version = '" + newVersion + "'")
    buildFile.setText(s)
}

在命令下运行时，

/home/user/gradle-5.1.1/bin/gradle clean build

，

incrementSnapshotVersion

任务也正在运行，版本意外更新。

还尝试了

-x incrementSnapshotVersion

，但文件中的版本仍会增加，但是，从build.gradle中删除

incrementSnapshotVersion

后，版本仍保持原样。

现在，版本将在配置阶段增加，这就是为什么每次运行命令时，版本都会增加的原因

task incrementSnapshotVersion {
    doFirst {
        String jVersion = version
        int snapshotSuffixBegin = jVersion.lastIndexOf('-')
        String currentMinor = jVersion.substring(jVersion.lastIndexOf('.') + 1, snapshotSuffixBegin)
        String updatedMinor = (Integer.parseInt(currentMinor) + 1).toString()
        String major = jVersion.substring(0, jVersion.lastIndexOf(currentMinor))
        String newVersion = major + updatedMinor + "-SNAPSHOT"
        String s = buildFile.getText().replaceFirst("version = '$jVersion'", "version = '" + newVersion + "'")
        buildFile.setText(s)
    }
}

你必须把这种行为放在任务的行动中

这样，只有当您将使用

/gradlew incrementSnapshotVersion

执行任务，或者执行依赖的任务，或者由您的任务完成时，版本才会增加

task incrementSnapshotVersion {
    doFirst {
        String jVersion = version
        int snapshotSuffixBegin = jVersion.lastIndexOf('-')
        String currentMinor = jVersion.substring(jVersion.lastIndexOf('.') + 1, snapshotSuffixBegin)
        String updatedMinor = (Integer.parseInt(currentMinor) + 1).toString()
        String major = jVersion.substring(0, jVersion.lastIndexOf(currentMinor))
        String newVersion = major + updatedMinor + "-SNAPSHOT"
        String s = buildFile.getText().replaceFirst("version = '$jVersion'", "version = '" + newVersion + "'")
        buildFile.setText(s)
    }
}
