JFans Java Fans <<<《中国人的智慧》 | 首页 | eclipse中运行ant出现junit执行错误的解决办法时间: 2004-09-18 当build.xml中包含有任务时，直接在eclipse下Run Ant Build会出现错误，错误内容如下： BUILD FAILED: [ECLIPSE_DIR]\workspace[PROJECT_DIR]\build.xml:208: Could not create task or type of type: junit. Ant could not find the task or a class this task relies upon. This is common and has a number of causes; the usual solutions are to read the manual pages then download and install needed JAR files, or fix the build file:

You have misspelt 'junit'. Fix: check your spelling.
The task needs an external JAR file to execute and this is not found at the right place in the classpath. Fix: check the documentation for dependencies. Fix: declare the task.
The task is an Ant optional task and optional.jar is absent Fix: look for optional.jar in ANT_HOME/lib, download if needed
The task was not built into optional.jar as dependent libraries were not found at build time. Fix: look in the JAR to verify, then rebuild with the needed libraries, or download a release version from apache.org
The build file was written for a later version of Ant Fix: upgrade to at least the latest release version of Ant
The task is not an Ant core or optional task and needs to be declared using . Remember that for JAR files to be visible to Ant tasks implemented in ANT_HOME/lib, the files must be in the same directory or on the classpath Please neither file bug reports on this problem, nor email the Ant mailing lists, until all of these causes have been explored, as this is not an Ant bug. 这是因为任务在ant中是一个optional task（可选任务），并非core task（核心任务），所以我们需要junit相关支持，也就是junit.jar。在eclipse中，选择菜单 Window --> Preferences --> Ant --> Runtime --> Global Entries 在这里加入junit.jar，这时在eclipse中运行ant时会加载junit.jar，从而解决这个问题。 jfans 发表于 2004-09-18 21:41 引用(Trackback0) | 编辑评论发表评论最后更新
