我有一个自定义任务，它读取在项目的build.gradle中定义的变量，然后将这些值传递给maven-publish任务，以便它可以在适当的位置发布工件。
问题：
当我运行自定义任务时，它会抛出一个错误
org.gradle.api.InvalidUserDataException: Cannot configure the 'publishing' extension after it has been accessed.
当我从 getProject().gradle.taskGraph.whenReady 调用 publishTask（） 时。
目的：
在我的自定义任务从 build.gradle 文件中获取值后运行 maven-publish 任务。（gradle 在生成图表之前不会填充这些值，我可能是错的，因为我不太熟悉 gradle 开发）

解决方案是使用惰性 GString。这解决了 maven-publish 任务在 gradle 配置阶段获得空/空值的问题，因为 gradle 图尚未完全生成。使用惰性gStrings可以解决这个问题。所以时髦的代码看起来像这样：
def populateVariablesValue() {
def remoteURL = "${->project._remoteArtifactRepoURL}";
def localURL = "${->project._localDiskArtifactRepoURL}";
def arID = "${->project._artifactID}";
def gID = "${->project._groupID}";
def pushToRemote = "${->project._pushToRemoteArtifactRepo}";
this._artifactID = arID.size() > 0 ? arID: "PLEASE PROVIDE ARTIFACT ID!";
this._groupID = gID > 0 ? gID : "PLEASE PROVIDE GROUP ID!";
this.remoteArtifactRepoURL = remoteURL.size() > 0 ? remoteURL : "PLEASE PROVIDE REMOTE REPO URL";
this.localDiskArtifactRepoURL = localURL.size() > 0 ? localURL : "PLEASE PROVIDE LOCAL DISK REPO URL";
this.pushToRemoteArtifactRepo = pushToRemote;
println "INSIDE POPULATE VARIABLES VALUES:: _groupID "+ _groupID + " _artifactId: "+ _artifactID + " pushToRemote: "+ "${->project._pushToRemoteArtifactRepo}"
}
def getRepoUrl() {
println "inside getRepoURL"
println "inside pushToRemoteArtifactRepo: "+ pushToRemoteArtifactRepo
println "inside remoteArtifactRepoURL: "+ remoteArtifactRepoURL
println "inside localDiskArtifactRepoURL: "+ localDiskArtifactRepoURL
return (pushToRemoteArtifactRepo ? remoteArtifactRepoURL : localDiskArtifactRepoURL);
}
