m2e-wtp error: <path>/target/m2e-wtp/web-resources/META-INF/MANIFEST.MF (No such file or directory)
提问by Jelle van Geuns
I use m2e 1.2.0 and m2e-wtp 0.16.0, and occasionally my Eclipse build fails with the error:
我使用 m2e 1.2.0 和 m2e-wtp 0.16.0，偶尔我的 Eclipse 构建失败并显示错误：
<path>/target/m2e-wtp/web-resources/META-INF/MANIFEST.MF (No such file or directory)
The problem can be temporarily solved by doing a Maven->Update project..., but the error will come back after a while. Not sure what exactly the trigger is....
问题可以通过做一个 暂时解决Maven->Update project...，但过一段时间又会出现错误。不知道具体是什么触发....
Any suggestions on how to fix the issue permanently?
关于如何永久解决问题的任何建议？
[Edit] I found that the issue is triggered when I build the project externally using the Maven command line directly. This will remove the default MANIFEST.MF that m2e-wtp generates, and it apparently doesn't get regenerated until you do a rebuild in Eclipse.
[编辑]我发现当我直接使用Maven命令行在外部构建项目时会触发该问题。这将删除 m2e-wtp 生成的默认 MANIFEST.MF，并且在您在 Eclipse 中进行重建之前它显然不会重新生成。

Eclipse versions earlier than Luna
早于 Luna 的 Eclipse 版本
I'm not certain if this is the best thing to do but I followed the instructions mentioned herewith regards to getting rid of the auto generated web resources folder and this seems to also resolve the issue with the missing MANIFEST.MF:
我不确定这是否是最好的做法，但我遵循了此处提到的 有关摆脱自动生成的 Web 资源文件夹的说明，这似乎也解决了缺少 MANIFEST.MF 的问题：
- on your project only : right-click on the project > Properties > Maven > WTP : check "Enable Project Specific Settings" and uncheck "Maven Archiver generates files under the build directory"
- on the whole workspace : Window > Preferences > Maven > WTP : uncheck "Maven Archiver generates files under the build directory"
- 仅在您的项目上：右键单击项目 > 属性 > Maven > WTP：选中“启用项目特定设置”并取消选中“Maven Archiver 在构建目录下生成文件”
- 在整个工作区：窗口 > 首选项 > Maven > WTP：取消选中“Maven Archiver 在构建目录下生成文件”
We actually generate our manifest entries as part of the maven-war-plugin when we actually want to package/build the project, but I dont think m2e-wtp uses this. In any event, the manifest file is irrelevant for us in the build that m2e-wtp creates for use within eclipse.
当我们真正想要打包/构建项目时，我们实际上将清单条目生成为 maven-war-plugin 的一部分，但我不认为 m2e-wtp 使用它。无论如何，在 m2e-wtp 为在 eclipse 中使用而创建的构建中，清单文件与我们无关。
Eclipse Luna and later
Eclipse Luna 及更高版本
For Eclipse Luna you have to go:
对于 Eclipse Luna，你必须去：
Preferences > Maven > Java EE Integration and uncheck "Maven Archiver generates files under the build directory".
首选项 > Maven > Java EE 集成并取消选中“Maven Archiver 在构建目录下生成文件”。
Eclipse Luna does not have the path at project Properties and the WTP section
Eclipse Luna 在项目属性和 WTP 部分没有路径

This solution works for me Rightclick on Project --> Properties --> Maven --> Java EE Integration --> check enable project specific settings and disable Maven archiver generates files
此解决方案适用于我右键单击项目 --> 属性 --> Maven --> Java EE 集成 --> 检查启用项目特定设置并禁用 Maven 归档程序生成文件

Try to select your project, and clean it by using the menu :
尝试选择您的项目，并使用菜单清理它：
Project>Clean

Right click on Your Project, go to properties and then to Project Facets, now go to Runtime tab on the right and select the server and click on apply, the error message would be gone.
右键单击您的项目，转到属性，然后转到 Project Facets，现在转到右侧的运行时选项卡并选择服务器并单击应用，错误消息将消失。

manifest.mf is getting destroyed when we try to do maven build using mvn cleaninstall. If we don't want to destroy manifest.mf file, just enter the command mvn install in the command prompt.
当我们尝试使用 mvn cleaninstall进行 maven 构建时，manifest.mf 被破坏了。如果我们不想破坏 manifest.mf 文件，只需在命令提示符中输入命令 mvn install 即可。
And if we missed the manifest.mf file, we can generate by uncheck & check the "Maven archiver generates files under the build directory" option in maven - JAVA EE integration as you said.
如果我们错过了 manifest.mf 文件，我们可以通过取消选中并选中 maven - JAVA EE 集成中的“Maven 归档程序在构建目录下生成文件”选项来生成，如您所说。
