ant build java程序找不到目标
[英]ant build java program could not find targets
问题描述
I am maintaining a java program that is not mine. 
我正在维护一个不是我的Java程序。 I used eclipse and I could build the program with Ant. 我使用了eclipse，可以用Ant构建程序。 I don't know very much about Ant. 我对蚂蚁不太了解。 Everything was installed fine on my eclipse IDE and the build worked perfect till today. 一切在我的Eclipse IDE上都安装得很好，并且该构建到目前为止一直运行良好。 I didn't change anything, so I don't know why it doesn't work anymore. 我没有做任何更改，所以我不知道为什么它不再起作用了。
When I look at the external Tools Configurations,I see that the targets are missing. 当我查看外部工具配置时，我发现目标丢失了。 I have the message "No targets could be determined for the build file". 我收到消息“无法为构建文件确定目标”。 Previously I could select some targets. 以前，我可以选择一些目标。 Does someone know how it come that the targets disappeared? 有人知道目标消失的原因吗？

I fixed it by switching the eclipse workspace. 我通过切换Eclipse工作区来修复它。 I went to menu File->Switch Workspace->Other, and then I have selected the same workspace I was working with. 我转到菜单文件->切换工作区->其他，然后选择了我正在使用的相同工作区。 Eclipse restarted and the error wasn't there anymore. Eclipse重新启动，错误不再存在。

这对我有所帮助：从Ant视图中删除构建文件，然后再次添加。
