如何用Groovy在Active Choices Parameters中连接SVN获取Jar生成下拉选项？

Absolutely! You can modify your Groovy script to connect to an SVN repository using a username and password, list the contents of a specified directory, filter for .jar files, and populate your dropdown menu. Here's how to do it:

Prerequisite #

First, ensure that SVNKit (the Java-based SVN library) is available in your Jenkins instance's classpath. Most Jenkins installations with the Subversion plugin already include this, but if not, you may need to add the SVNKit JAR to $JENKINS_HOME/lib/ and restart Jenkins.

Groovy Script for SVN Jar Fetching #

import org.tmatesoft.svn.core.SVNURL
import org.tmatesoft.svn.core.auth.ISVNAuthenticationManager
import org.tmatesoft.svn.core.internal.io.dav.DAVRepositoryFactory
import org.tmatesoft.svn.core.internal.io.fs.FSRepositoryFactory
import org.tmatesoft.svn.core.internal.io.svn.SVNRepositoryFactoryImpl
import org.tmatesoft.svn.core.io.SVNRepository
import org.tmatesoft.svn.core.io.SVNRepositoryFactory
import org.tmatesoft.svn.core.wc.SVNWCUtil

// Initialize SVN repository factories to support all protocols
DAVRepositoryFactory.setup()
SVNRepositoryFactoryImpl.setup()
FSRepositoryFactory.setup()

// Configuration - update these values to match your SVN setup!
def svnUrl = "https://your-svn-server/path/to/target/jar/directory"
def username = "your-svn-username"
def password = "your-svn-password"

def jarFiles = []

try {
    // Create a connection to the SVN repository
    SVNRepository repository = SVNRepositoryFactory.create(SVNURL.parseURIEncoded(svnUrl))
    
    // Set up authentication with your credentials
    ISVNAuthenticationManager authManager = SVNWCUtil.createDefaultAuthenticationManager(username, password.toCharArray())
    repository.setAuthenticationManager(authManager)
    
    // Fetch all entries in the specified SVN directory (revision -1 means latest)
    def entries = repository.getDir("", -1, null, (Collection) null)
    
    // Filter entries to only include .jar files and collect their names
    entries.each { entry ->
        if (entry.name.endsWith(".jar")) {
            jarFiles.add(entry.name)
        }
    }
    
    // Sort the list alphabetically for consistency
    jarFiles = jarFiles.sort()
} catch (Exception e) {
    // Handle errors gracefully by showing an error message in the dropdown
    jarFiles.add("Error: " + e.getMessage())
}

return jarFiles

Key Notes: #

• Update Configuration Values: Replace svnUrl, username, and password with your actual SVN details.
• Error Handling: The script includes basic error handling to display a meaningful message in the dropdown if something goes wrong (e.g., invalid credentials, connection issues).
• Protocol Support: This script works with http://, https://, svn://, and file:// SVN URLs, thanks to the initialized factories.
• Security Tip: Storing plain-text passwords directly in the script isn't ideal. For better security, use Jenkins' credential store to retrieve passwords securely (you can leverage the com.cloudbees.plugins.credentials.CredentialsProvider class in Groovy to fetch stored credentials).
