使用 Groovy，如何捕获运行另一个进程的 shell 命令的控制台输出（System.out和）？System.err

实际上，我正在运行prettier使用并尝试捕获两个进程的输出，就像我在 shell 中yarn运行命令时看到的那样。yarn

运行yarn prettier --check .收益率

yarn run v1.22.17
$ /my-project/node_modules/.bin/prettier --check .
Checking formatting...
[warn] some-file.ts
[warn] another-file.ts
[warn] Code style issues found in 2 files. Run Prettier with --write to fix.
error Command failed with exit code 1.
info Visit https://yarnpkg.com/en/docs/cli/run for documentation about this command.

这是我想要捕获的输出。但是，Groovy 代码

def check = "yarn prettier --check .".execute()
check.waitFor()
println check.getText()

仅产生

yarn run v1.22.17
$ /my-project/node_modules/.bin/prettier --check .
Checking formatting...
info Visit https://yarnpkg.com/en/docs/cli/run for documentation about this command.

缺少 Prettier 的输出。在我看来，Groovy 似乎只捕获了 Yarn 进程的输出，而不是 Yarn 生成的 Prettier 进程的输出。

是否也可以捕获 Prettier 中缺失的输出？我意识到我可以直接从 Groovy 运行 Prettier，但由于其他配置，我想避免这样做。

我们有一个大型的 Spock 测试套件，跨多个团队，每个团队的测试都有一个注释，例如@Team5。

我想- @Team5动态地将该注释附加到每个标有该注释的测试方法名称的末尾，以便在报告测试失败时轻松看出哪个团队对每次失败负责。

我已经研究过编写 spock 扩展，但似乎找不到任何可以实际修改功能名称的地方，我是不是遗漏了什么？

我目前在 Jira Scriptrunner 中使用 Groovy。我正在使用 apache 中的 XSSFWorkbook。在脚本中，我加载一个“模板”.xslx 文件，然后使用脚本对其进行修改。尽管该文件从未以相同的文件名保存到服务器，但仅workbook.write(outputStream)被workbook.close()调用，服务器上的原始文件已被修改。

以下是代码：

import org.apache.poi.xssf.usermodel.XSSFWorkbook
import releasemanagement.changes.AttachmentCreator
import other.TMPConfig
import com.atlassian.jira.issue.fields.CustomField
import com.atlassian.jira.issue.CustomFieldManager
import com.atlassian.jira.component.ComponentAccessor
import org.apache.poi.xssf.usermodel.XSSFCell

CustomFieldManager custFldManag = ComponentAccessor.getCustomFieldManager()

def issue = Issues.getByKey("ISSUEKEY")

def attachmentCreator = new AttachmentCreator()
def attachmentManager = ComponentAccessor.getAttachmentManager()

def wb = new XSSFWorkbook(new File("path/Template.xlsx"))

CustomField currCF
XSSFCell currCell
String reportType = "Initial"

TMPConfig.fieldToCell.each{k, v ->
    List<Integer> cellCoordinates = v.get(reportType)
    if(cellCoordinates){
        currCell = wb.getSheetAt(cellCoordinates[0]).getRow(cellCoordinates[1]).getCell(cellCoordinates[2])
        if(currCell){
            currCF = custFldManag.getCustomFieldObject(k)
            currCell.setCellValue(currCF.getValue(issue).toString())
        }
    }
}

ByteArrayOutputStream out = new ByteArrayOutputStream()
wb.write(out)
wb.close()
ByteArrayInputStream inputStream = new ByteArrayInputStream(out.toByteArray())
out.close()

int filename_num = 1
String filename = "Dora_${reportType}_${filename_num}.xlsx"

attachmentCreator.createAttachmentForIssue(issue, filename, "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet", inputStream)

目前，这个问题已由我的同事通过以下解决方法解决：

XSSFWorkbook wb_temp = new XSSFWorkbook(new File("path/Template.xlsx"))
    ByteArrayOutputStream out_temp = new ByteArrayOutputStream()
        wb_temp.write(out_temp)
        wb_temp.close()
    ByteArrayInputStream inputStream_temp = new ByteArrayInputStream(out_temp.toByteArray())
        out_temp.close()
    XSSFWorkbook wb = new XSSFWorkbook(inputStream_temp)

但我对这种行为的原因很感兴趣。我希望当它附加到问题中时，内存中的表示不会影响原始文件。感谢您的任何见解。

编写代码，发现get操作无法从具有枚举键的map中获取值。

例如，checkers初始化后，get操作总是返回 null。为什么

class Test {
    static void main(String[] args){
        Map<CHANA_OPERATION, Closure> checkers = [VIDEO_GENERATION: (userId) -> {
            System.out.println("..............")
        }, TEXT_API_CALL: (userId)->{
            return false
        }]

        checkers.get(CHANA_OPERATION.VIDEO_GENERATION).call(1)
    }


    enum CHANA_OPERATION{
        VIDEO_GENERATION(0),
        TEXT_API_CALL(1),
        TEXT_VIDEO_API_CALL(2)

        int code
        CHANA_OPERATION(int code){
            this.code = code
        }
    }

}

我创建Person如下：

public class Person {
    private String sCode;
    private String sDate;

    Person(String sCode, String sDate) {
        this.sCode = sCode;
        this.sDate = sDate;
    }// Constructor and other methods...

    @Override
    boolean equals(Object obj) {
        if (this == obj) return true;
        if (obj == null || getClass() != obj.getClass()) return false;
        Person oPerson = (Person) obj;
        return oPerson.sCode == this.sCode && oPerson.sDate == this.sDate;
    }

    @Override
    public int hashCode() {
        return Objects.hash(this.sCode, this.sDate);
    }
}

我想将Person对象存储在HashSet（personSet）中：

HashSet<Person> personSet = new HashSet<>();
Person person1 = new Person("Aman", "2021-01-01");
Person person2 = new Person("Aman", "2021-01-01");
personSet.add(person1);
personSet.add(person2);
System.out.println(personSet.size());  //Expected size to be "1"

但是我收到Caught: java.lang.StackOverflowError以下错误：

Caught: java.lang.StackOverflowError
java.lang.StackOverflowError
    at Person.equals(Person.groovy:12)

有人可以告诉我为什么我的代码会抛出这个错误吗？

我有以下测试代码，其中我创建了一个列表Map<String,String>并想要打印列表中每个映射的键/值。

#!/usr/local/bin/groovy

List<Map<String,String>> list = []
Map<String, String> map1 = ["a":"a"]
list.add(map1)
println list
Map<String, String> map2 = ["b":"b"]
list.add(map2)
println list
list.each { m->
  println "${m.key} ${m.value}"
}

执行代码时，我得到

[[a:a]]
[[a:a], [b:b]]
null null
null null

在列表中打印每个地图的键和值的正确方法是什么？

我对 channel.fromFilePairs() 有疑问。我有以下 nextflow 脚本：

params.reads = "/path/to/my_reads/sample03_L001_R{1,2}_001.fastq.gz"

my_reads_ch = channel.fromFilePairs(params.reads)

println "reads: $my_reads_ch"

该脚本打印 [sample03_L001_R, [/path/to/my_reads/sample03_L001_R1_001.fastq.gz, /path/to/my_reads/sample03_L001_R2_001.fastq.gz]].

所需输出是 [sample03, [/path/to/my_reads/sample03_L001_R1_001.fastq.gz, /path/to/my_reads/sample03_L001_R2_001.fastq.gz]].

我如何删除“_L001_R”？

我试过了

channel.fromFilePairs(params.reads).map{it[0] - /_\w+/, it[1]}

这给了我一个错误：模式类型上未知的方法调用“负面”。

有什么建议吗？非常感谢

我正在尝试使用 MarkupTemplateEngine 在 MJML 中渲染模板，但尝试了一段时间后我开始怀疑这是否可能。可能还是不可能？如果是的话，我想要一个可以测试的例子。

到目前为止我做了什么：

import groovy.text.markup.*

String mjmlTemplate = '''
mjml {
    mj-head {
        mj-title('Hello World')
        mj-preview('This is a preview text')
    }
    mj-body {
        mj-section {
            mj-column {
                mj-text('Hello World from MJML')
            }
        }
    }
}
'''

TemplateConfiguration config = new TemplateConfiguration();
MarkupTemplateEngine engine = new MarkupTemplateEngine(config);

def template = engine.createTemplate(mjmlTemplate)
def renderedMJML = template.make().toString()

println renderedMJML

我得到的错误：


Caught: java.lang.NullPointerException: Cannot invoke method minus() on null object

        at test.run(test.groovy:30)
        at java.base/jdk.internal.reflect.DirectMethodHandleAccessor.invoke(DirectMethodHandleAccessor.java:103)

如果我用渲染 HTML 进行测试，它工作得很好。

需要帮助识别计划线数组对象并将数量字段设置为删除“”的数字。我需要一些关于如何访问 _PurchaseOrderScheduleLineTP.ScheduleLineOrderQuantity 的指示

import com.sap.gateway.ip.core.customdev.util.Message;
import java.util.HashMap;
import groovy.json.*
def Message processData(Message message) {

def body = message.getBody(java.lang.String);
def object = new JsonSlurper().parseText(body)



object._PurchaseOrderItem.each{_PurchaseOrderItem->
_PurchaseOrderItem.NetPriceQuantity = _PurchaseOrderItem.NetPriceQuantity.toDouble().intValue()
_PurchaseOrderItem.NetAmount = _PurchaseOrderItem.NetAmount.toDouble()
_PurchaseOrderItem.GrossAmount = _PurchaseOrderItem.GrossAmount.toDouble()
_PurchaseOrderItem.OrderQuantity = _PurchaseOrderItem.OrderQuantity.toDouble()
_PurchaseOrderItem.NetPriceAmount = _PurchaseOrderItem.NetPriceAmount.toDouble()
}

object._PurchaseOrderItem.each{_PurchaseOrderItem->
_PurchaseOrderScheduleLineTP.each{_PurchaseOrderScheduleLineTP->
_PurchaseOrderScheduleLineTP.number =_PurchaseOrderScheduleLineTP.ScheduleLineOrderQuantity.toDouble().intValue()
}
}

//object._PurchaseOrderScheduleLineTP.each{_PurchaseOrderItem._PurchaseOrderScheduleLineTP->
//_PurchaseOrderScheduleLineTP.ScheduleLineOrderQuantity = _PurchaseOrderScheduleLineTP.ScheduleLineOrderQuantity.toDouble().intValue()

message.setBody(JsonOutput.toJson(object));

我正在尝试在 Groovy 中使用 Snakeyaml 解析 YAML 文件。目标是创建一个我最终可以搜索的地图。

我正在使用的文件结构如下：

maintainers:
  - component: PowerPuff Girls
    pg: Utonium Labs
    people:
      - Buttercup
      - Blossom
      - Bubbles
    files:
      - sugar/*
      - spice/*
      - things/*nice*
      - chemicalx/*
  - component: Gangreen Gang
    pg: Villians
    people:
      - Ace
      - Snake
      - Big Billy
    files:
      - ace/*
      - snake/*

问题是：当我创建地图并返回值时，该maintainers值与我希望的格式不同。此外，似乎没有任何字符串值被转换为字符串。输出是：

[maintainers:[[component:PowerPuff Girls, pg:Utonium Labs, people:[Buttercup, Blossom, Bubbles], files:[sugar/*, spice/*, things/*nice*, chemicalx/*]], [component:Gangreen Gang, pg:Villians, people:[Ace, Snake, Big Billy], files:[ace/*, snake/*]]]]

在一个完美的世界里，我会：

[component: 'PowerPuff Girls', pg: 'Utonium Labs', people: ['Buttercup', 'Blossom', 'Bubbles'], files: ['sugar/*','spice/*','things/*nice*', 'chemicalx']], 
[component: 'Gangreen Gang', pg: 'Villians', people: ['Ace', 'Snake', 'Big Billy'], files: ['ace/*','snake/*']]

我在重新格式化这张地图时一定错过了一些愚蠢的事情。我欢迎所有建议！

第 1 步：将文件加载为地图

Yaml yaml = new Yaml()
Map yamlMap = yaml.load(yamlFile)

步骤2：返回map以观察格式return yamlMap

结果是：

[maintainers:[[component:PowerPuff Girls, pg:Utonium Labs, people:[Buttercup, Blossom, Bubbles], files:[sugar/*, spice/*, things/*nice*, chemicalx/*]], [component:Gangreen Gang, pg:Villians, people:[Ace, Snake, Big Billy], files:[ace/*, snake/*]]]]

我尝试分别定义各个键和值并重建它们，但它没有按预期拉动分组。例如：def myVariable = yamlMap['maintainers']['component']
