如何克服 Maven minify 插件的 "object literals cannot contain duplicate keys in ES5 strict mode" 错误?

How do I overcome "object literals cannot contain duplicate keys in ES5 strict mode" error with Maven minify plugin?

我在 Maven 3.5 中使用 Maven minify 插件。我有以下配置...

                <plugin>
                    <groupId>com.samaxes.maven</groupId>
                    <artifactId>minify-maven-plugin</artifactId>
                    <version>1.7.6</version>
                    <executions>
                        <execution>
                            <id>default-minify</id>
                            <phase>verify</phase>
                            <configuration>
                                <cssSourceIncludes>
                                    <cssSourceInclude>**/*.css</cssSourceInclude>
                                </cssSourceIncludes>
                                <cssTargetDir>../${project.artifactId}/css</cssTargetDir>
                                <jsSourceExcludes>
                                    <jsSourceExclude>lib/pdf.js</jsSourceExclude>
                                    <jsSourceExclude>lib/pdf.worker.js</jsSourceExclude>
                                    <jsSourceExclude>ckeditor_4.2/**</jsSourceExclude>
                                    <jsSourceExclude>geogebra/**</jsSourceExclude>
                                    <jsSourceExclude>contextMenu/**</jsSourceExclude>
                                    <jsSourceExclude>wPaint/**</jsSourceExclude>
                                </jsSourceExcludes>
                                <jsSourceIncludes>
                                    <jsSourceInclude>**/*.js</jsSourceInclude>
                                </jsSourceIncludes>
                                <jsTargetDir>../${project.artifactId}/js</jsTargetDir>
                                <jsEngine>CLOSURE</jsEngine>
                                <webappTargetDir>${project.build.outputDirectory}</webappTargetDir>
                                <skipMerge>true</skipMerge>
                                <nosuffix>true</nosuffix>
                            </configuration>
                            <goals>
                                <goal>minify</goal>
                            </goals>
                        </execution>
                    </executions>
                </plugin>

但是,我在以下文件中收到此错误...

SEVERE: panel.js:845: ERROR -  with         

    SIDE_PANEL_BEGIN_CLOSE_EVENT:SIDE_PANEL_BEGIN_CLOSE_EVENT,
            ^

    WARNING: 1 error(s), 0 warning(s)

我的未压缩文件在我的应用程序中一切正常,所以我认为我的配置有误,但我看不到什么。如何更正配置,以便在不影响代码的基础功能的情况下进行优化而不出错?

虽然 Google 的 Closure 编译器(由 minify 插件在后台使用它来优化源代码)默认情况下期望 ECMAScript 6 作为输入语言,但它似乎 运行 额外 diagnostic checks不考虑语言水平

这些诊断检查包括一项针对 ECMAScript 5 严格模式合规性的检查,该检查禁止对象中的重复键。

中所述,您可以通过添加

在缩小配置中打开此诊断检查
<closureWarningLevels>
    <es5Strict>OFF</es5Script>
</closureWarningLevels>
