v1/cmd/deploy/suggestions.go (4)
26-35: Follow Go naming conventions for constants.The constant name
faq_urlshould be in uppercase with underscores for Go constants, likeFAQ_URL.- faq_url = "https://koupleless.io/en/docs/faq/faq/" + FAQ_URL = "https://koupleless.io/en/docs/faq/faq/"The modular design using a slice of suggestion functions is excellent for extensibility.
41-57: Consider enhancing error handling and suggestion relevance.A few suggestions for improvement:
- The FAQ URL is always printed, even if a specific suggestion was found. Consider making it conditional.
- There's no handling for nil error input.
Consider this improvement:
func printSuggestionWithMore(err error, subprocessOutput []string) { + if err == nil { + return + } var errorOutputLines []string if lines := strings.Split(err.Error(), "\n"); len(lines) > 0 { errorOutputLines = append(errorOutputLines, lines...) } if len(subprocessOutput) > 0 { errorOutputLines = append(errorOutputLines, subprocessOutput...) } + suggestionFound := false for _, suggestionFunc := range suggestionFuncs { if suggestionFunc(errorOutputLines) { + suggestionFound = true break } } + // Only show FAQ URL if no specific suggestion was found + if !suggestionFound { doPrintSuggestion("you can go to faq for more help at " + faq_url) + } }
59-74: Enhance base connection error detection.The current implementation might miss some connection refused errors. Consider checking for additional connection error patterns.
func suggestionBaseNotStart(errorOutputLines []string) bool { hasBaseNotStart := false for _, line := range errorOutputLines { - if strings.HasSuffix(line, "connect: connection refused") { + if strings.Contains(line, "connect: connection refused") || + strings.Contains(line, "connection reset by peer") || + strings.Contains(line, "no route to host") { if strings.Contains(line, "installBiz") { hasBaseNotStart = true break
1-138: Consider enhancing the error diagnosis architecture.The current architecture is well-structured but could be enhanced:
- Consider introducing an interface for suggestion functions to allow for more complex suggestion implementations
- Add support for suggestion priorities or categories
- Consider adding telemetry to track which errors are most common
Example interface design:
type Suggestion interface { // Match checks if this suggestion applies to the given error Match(errorLines []string) bool // GetMessage returns the suggestion message GetMessage() string // GetPriority returns the suggestion priority GetPriority() int }v1/cmd/deploy/deploy.go (1)
129-134: Consider adding capacity hint for mvnOutput sliceThe mvnOutput slice grows without bounds as it captures Maven output. For large builds, this could lead to excessive memory usage.
- mvnOutput := []string{} + mvnOutput := make([]string, 0, 1000) // Provide initial capacity estimate

1-24: LGTM! Clean package structure and imports.
The file has proper licensing and minimal necessary imports.
136-138: LGTM! Clean and focused helper function.
The function provides consistent styling for suggestions using the style package.
91-112: Consider version comparison for Maven version check.
Instead of relying on error message patterns, consider adding actual version comparison logic for more accurate Maven version detection.
Let's verify the Maven version detection patterns:
v1/cmd/deploy/deploy.go (4)
377-379: LGTM: Enhanced error handling with suggestions
Good addition of error suggestions to help users troubleshoot uninstallation failures.
397-399: LGTM: Consistent error handling pattern
Good addition of error suggestions, maintaining consistency with the uninstallation error handling pattern.
125-125: Verify suggestion functions implementation
The code relies on printSuggestion and printSuggestionWithMore functions that are not visible in this file. Please ensure these functions:
- Handle all common error scenarios
- Provide actionable suggestions
- Include proper error categorization
Also applies to: 139-139, 145-145, 377-377, 397-397
✅ Verification successful
Let me gather more information about the suggestion functions and error handling patterns.
Error handling implementation verified and well-structured
The suggestion functions are properly implemented with:
- Clear error categorization covering common scenarios:
- Base application not running
- Maven executable missing
- Maven version compatibility
- Web context path conflicts
- Actionable suggestions provided for each error case
- Consistent error handling pattern with fallback to FAQ documentation
The implementation follows good practices by:
- Processing both single-line and multi-line errors
- Supporting additional subprocess output
- Breaking after first matching suggestion
- Providing a default fallback to documentation

Length of output: 4546
130-135: Verify goroutine cleanup
The goroutine reading from mvn.Output() should terminate properly when the channel is closed. Please verify that cmdutil.BuildCommandWithWorkDir properly closes its output channel in all scenarios.
✅ Verification successful
Let me search for more specific information about the channel handling in the codebase.
Let me search for the complete implementation of the command struct and its methods to understand how these channels are managed.
Let me search for the implementation of command methods, particularly focusing on the execution and channel management.
Let me try one more search to find the command execution and channel management code.
Goroutine cleanup is properly handled
The implementation in common/cmdutil/cmd_util.go shows that the output channel is properly managed:
- The output channel is closed after the stdout scanning is complete
- The command execution and error handling are properly managed through context cancellation
- The completeSignal channel is properly closed with error handling

26-28: Follow Go naming conventions for constantsThe constant
faq_urlshould be renamed tofaqURLto follow Go naming conventions for constants and acronyms.const ( - faq_url = "https://koupleless.io/en/docs/faq/faq/" + faqURL = "https://koupleless.io/en/docs/faq/faq/" )
43-61: Improve suggestion handling logicThe function could be enhanced in several ways:
- Track whether any specific suggestions were made
- Only show the FAQ URL if no specific suggestions were found
- Add error documentation
func printSuggestionWithMore(err error, subprocessOutput []string) { var errorOutputLines []string if err != nil { if lines := strings.Split(err.Error(), "\n"); len(lines) > 0 { errorOutputLines = append(errorOutputLines, lines...) } } if len(subprocessOutput) > 0 { errorOutputLines = append(errorOutputLines, subprocessOutput...) } + suggestionFound := false for _, suggestionFunc := range suggestionFuncs { if suggestionFunc(errorOutputLines) { + suggestionFound = true break } } + // Only show FAQ URL if no specific suggestions were found + if !suggestionFound { doPrintSuggestion("you can go to faq for more help at " + faqURL) + } }
63-148: Improve error message matching robustnessThe error matching logic across multiple functions could be improved:
- Add case-insensitive matching
- Create a common utility for error pattern matching
- Consider using regular expressions for more flexible matching
Consider creating a utility function for error matching:
func containsErrorPattern(line, pattern string) bool { return strings.Contains(strings.ToLower(line), strings.ToLower(pattern)) } // Example usage in suggestionBaseNotStart func suggestionBaseNotStart(errorOutputLines []string) bool { for _, line := range errorOutputLines { if containsErrorPattern(line, "connect: connection refused") && containsErrorPattern(line, "installBiz") { doPrintSuggestion("ensure target base is running") return true } } return false }
39-41: Add observability for error diagnosisConsider enhancing the error diagnosis system with:
- Structured logging for unhandled errors
- Metrics to track which suggestions are most common
- Metrics to track suggestion effectiveness
This would help in:
- Understanding which errors users commonly encounter
- Identifying gaps in error handling
- Improving suggestion accuracy over time

🛠️ Refactor suggestion
Fix typo and improve error message matching
- There's a typo in the suggestion message: "sprign-boot" should be "spring-boot"
- The string matching is tightly coupled to specific error messages, which might break if the upstream error messages change
- doPrintSuggestion("import sprign-boot-actuator-autoconfiguration artifact in your pom.xml file")
+ doPrintSuggestion("import spring-boot-actuator-autoconfiguration artifact in your pom.xml file")Consider extracting error message patterns into constants and using more flexible pattern matching:
+const (
+ startupEndpointClass = "org.springframework.boot.actuate.autoconfigure.startup.StartupEndpointAutoConfiguration"
+ autoConfigError = "The following classes could not be excluded because they are not auto-configuration classes"
+)
func suggestImportSpringBootAutoConfiguration(errorOutputLines []string) bool {

🛠️ Refactor suggestion
Refactor suggestion functions to reduce duplication and improve maintainability
The suggestion functions follow similar patterns and could benefit from:
- A common error matching utility function
- Constants for error patterns
- More structured suggestion messages
Consider this approach:
+type ErrorPattern struct {
+ pattern string
+ subPattern string // optional
+ suggestion string
+}
+
+var (
+ baseNotStartPattern = ErrorPattern{
+ pattern: "connect: connection refused",
+ subPattern: "installBiz",
+ suggestion: "ensure target base is running",
+ }
+ // Add other patterns...
+)
+
+func matchErrorPattern(lines []string, pattern ErrorPattern) bool {
+ for _, line := range lines {
+ if strings.Contains(line, pattern.pattern) {
+ if pattern.subPattern == "" || strings.Contains(line, pattern.subPattern) {
+ doPrintSuggestion(pattern.suggestion)
+ return true
+ }
+ }
+ }
+ return false
+}This would simplify the suggestion functions:
func suggestionBaseNotStart(errorOutputLines []string) bool {
- hasBaseNotStart := false
- for _, line := range errorOutputLines {
- if strings.HasSuffix(line, "connect: connection refused") {
- if strings.Contains(line, "installBiz") {
- hasBaseNotStart = true
- break
- }
- }
- }
- if hasBaseNotStart {
- doPrintSuggestion("ensure target base is running")
- return true
- }
- return false
+ return matchErrorPattern(errorOutputLines, baseNotStartPattern)

感谢 PR，诊断规则库来自于这篇文档 https://koupleless.io/docs/faq/faq/ ，要能根据这里的文档自动识别，从文档库里提取给出错误原因和解决方案。最后补上文档链接地址 |
是的，我的 pr 里的方案就是根据这篇 FAQ文档，通过检测 arkctl deploy 命令在运行失败时的控制台输出文案里的特定模式，给出对应的解决方案提示。 |
|
我实验了下，我用一个完全没有做模块瘦身的模块来安装，报错如下： 但是没有看到 arkctl 提取出 faq 文档里的错误诊断和解决方案，faq 文档里已有的错误诊断和解决方案
所以 当前还缺少这部分功能 ，另外 关于 mvn 的错误，在没有增加 |
嗯，目前已经支持了下面这些问题的模式检测和根据faq文档输出修复提示的能力。其它的case 还需要继续补充。 另外原有的当前进程或子进程的报错信息也还是会输出到控制台的，没有变化。这个pr只是补充提供了一些问题修复建议。 |
了解了，但是这样的方式难以维护，faq 增加了错误条目，还需要手工再这里添加然后需要频繁发布新版本，用户也不一定为升级 arkctl 的版本。 比较理想的是可以直接提取 faq 里的问题报错，直接进行匹配，然后给出对应条目里的错误原因和解决方案。 |
考虑到实现的性价比，未归纳的错误信息提示到 faq |
