Java gwt maven插件即使在没有更改的情况下也会运行排列
我们在产品中使用GWT和mojo GWT maven插件2.4来编译GWT代码。 但是我们观察到,当我们运行mvn安装时,gwt maven插件正在运行排列,即使没有对gwt代码进行任何更改。 在这个问题上苦苦挣扎了一段时间后,我们能够使用2个maven项目通过简单的设置重现它: 第一个项目MygwtAventSampleSource:包含GWT代码和GWT模块xml文件 第二个项目MavenBuilderMod:包含MyGwtMavenSampleSource作为maven依赖项,并将构建war 文件 以下是两个项目的POM: 第一个项目:MyGwtMavenSampleSource 第二个项目:MavenBuilderMod 所以,问题是,我们如何让gwt maven插件/编译器在这种设置中只在代码更改时运行排列Java gwt maven插件即使在没有更改的情况下也会运行排列,java,eclipse,maven,gwt,plugins,Java,Eclipse,Maven,Gwt,Plugins,我们在产品中使用GWT和mojo GWT maven插件2.4来编译GWT代码。 但是我们观察到,当我们运行mvn安装时,gwt maven插件正在运行排列,即使没有对gwt代码进行任何更改。 在这个问题上苦苦挣扎了一段时间后,我们能够使用2个maven项目通过简单的设置重现它: 第一个项目MygwtAventSampleSource:包含GWT代码和GWT模块xml文件 第二个项目MavenBuilderMod:包含MyGwtMavenSampleSource作为maven依赖项,并将构建wa
注意:这与预期一样有效,即如果gwt模块xml文件放在包含gwt maven插件的同一个maven模块中,则仅当代码发生更改时才会运行置换,而且gwt maven插件中的增量构建支持可能会被破坏,特别是如果您仍在使用一个2年以上的版本 gwt maven插件在某种程度上看到了gwt.xml文件在您的第一个模块的构建过程中发生了变化,理想情况下,如果没有任何变化,它实际上应该是无操作的;重新复制资源和/或重建JAR可能足以向下触发问题,尤其是比它生成的nocache.js文件更新的问题 我认为更好的设置是在第一个模块中运行GWTMaven插件,并将所有内容打包到ZIP或WAR中,然后将其用作WAR覆盖。不幸的是,这使运行DevMode变得有点困难,但是
