如何在 Maven 中使用 Groovy 插件访问变量

Question

我有一个在子模块中包含 React 的应用程序，我想使用存在于父模块中的 node.exe。

在父 POM 中，我定义了一个变量，其路径为 node.exe

<properties>
    <project.name>Corretor Online</project.name>
    <nodeBase>C:/col/COL</nodeBase>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

Obs.: 我想在 nodeBase 变量中使用 ${project.basedir}

并且我尝试在子 POM 中访问这些变量以作为 ProcessBuilder 方法中的参数传递：

<plugin>
            <groupId>org.codehaus.groovy.maven</groupId>
            <artifactId>gmaven-plugin</artifactId>
            <executions>
                <execution>
                    <id>webpack</id>
                    <phase>process-resources</phase>
                    <goals>
                        <goal>execute</goal>
                    </goals>
                    <configuration>
                        <source><![CDATA[
                                println "Compiling client code..."
                                def webpack = new ProcessBuilder(["" + nodeBase + "/node/node", "" + nodeBase + "/node_modules/webpack/bin/webpack.js", "-p", "&#45;&#45;progress", "&#45;&#45;bail"]).inheritIO().directory(project.getBasedir())
                                def env = webpack.environment()
                                env.put("WAR_NAME", project.build.finalName)
                                def proc_webpack = webpack.start()
                                proc_webpack.waitForOrKill(120000)
                                if(proc_webpack.exitValue() != 0)
                                    throw new org.apache.maven.plugin.MojoFailureException("Error compiling client code")
                            ]]></source>
                    </configuration>
                </execution>
            </executions>
        </plugin>

但是我收到这个错误：

[ERROR] Failed to execute goal org.codehaus.groovy.maven:gmaven-plugin:1.0:execute (webpack) on project col-backoffice-war: groovy.lang.MissingPropertyException: No such property: nodeBase for class: script1539714060887 -> [Help 1]

如果我从 "nodeBase" 更改为“${nodeBase}，我会收到此错误：

[ERROR] Failed to execute goal org.codehaus.groovy.maven:gmaven-plugin:1.0:execute (webpack) on project col-backoffice-war: startup failed, script1539714572018.groovy: 2: unexpected char: '#' @ line 2, column 134.

但是，如果我输入文字路径，我可以构建。

def webpack = new ProcessBuilder(["C:/col/COL/node/node", 
"C:/col/COL/node_modules/webpack/bin/webpack.js", "-p", 
"&#45;&#45;progress", 
"&#45;&#45;bail"]).inheritIO().directory(project.getBasedir())

我找不到解决方案，你能帮我看看如何访问这个变量吗？

非常感谢！

我发现了问题。

需要将参数放在引号内，如下例

    def webpack = new ProcessBuilder("${nodeBase}" + "/node/node", "C:/col/COL/node_modules/webpack/bin/webpack.js", "-p", "&#45;&#45;progress", "&#45;&#45;bail"]).inheritIO().directory(project.getBasedir())
