Question

我需要帮助使用'maven-publish'插件发布工件。我使用它，因为我的下一步是发布项目的几个工件和'maven'插件几乎不适用于那种情况。所以请不要建议使用它。如果我使用变量来设置版本然后gradle失败并出现错误的问题。如果我指定固定值它工作正常如果我使用变量它不起作用。我如何将版本从变量传递到出版物？

相关代码：

println "project.version = $project.version"
ext.artifactVersion = String.valueOf(project.version);

println "artifactVersion = $artifactVersion" // to check that value is correct

publishing {
    publications {
        //publishArtifact(project)  
        maven(MavenPublication) {
            groupId project.group
            artifactId project.ext.artifactId

            println artifactVersion
            String artifactVersion2 = artifactVersion
            //version "1248"             // works
            //version artifactVersion    // doesn't work 
            //version "$artifactVersion" // doesn't work
            //version ''+artifactVersion // doesn't work
            //version '1248'             // works
            //version
            version "${artifactVersion}" // doesn't work 
            from project.components.java
        } 
    }
}

输出：

project.version = 1248
artifactVersion = 1248
1248

* What went wrong:
Execution failed for task ':prj:publishMavenPublicationToMavenLocal'.
> Failed to publish publication 'maven' to repository 'MavenLocal'
    > Invalid publication 'maven': supplied version does not match POM file (cannot edit version directly in the POM file).

感谢所有人研究问题。我找到了问题，并在此处发布结果，希望它能帮到某人。版本不能包含空格的问题的原因。在我的情况下，版本包含我没有注意到的尾随空格。它看起来像Gradle修剪从生成的pom读取它的值，然后比较它以检查值是否更改。希望这有助于节省时间。

ext.artifactVersion = String.valueOf(project.version).trim();

Gradle maven-publish插件不允许设置版本
