标签: failonerror

我有一个包含嵌入式javascript的ant任务.我希望基于我在javascript中运行的一些逻辑使目标失败或成功:

<target name="analyze">
    <script language="javascript">
    <![CDATA[
            importClass(java.io.File);
            importClass(java.io.FileReader)
            importClass(java.io.BufferedReader)

            String.prototype.startsWith = function(str) {
                return (this.indexOf(str) === 0);
            }

            String.prototype.endsWith = function(str) {
                var lastIndex = this.lastIndexOf(str);
                return (lastIndex != -1) && (lastIndex + str.length == this.length);
            }

            //setup the source directory
            srcDir = project.getProperty("MY_HOME") + "/foo/src";

            if(srcDir.startsWith("/foo") { 
            //TARGET SHOULD PASS
            } else { 
            //TARGET SHOULD FAIL
            }

    ]]>
    </script>
</target>

在我的环境中,我在Config.groovy上有grails.gorm.failOnError = true.

package org.example

class Book {

    String title
    String author
    String email

    static constraints = {
        title nullable: false, blank: false
        email nullable: false, blank: false, unique: true //apparently this is the problem..
    }
}

而且,在控制器上,我有:

package org.example

class BookController {

def update() {

        def bookInstance = Book.get(params.id)
        if (!bookInstance) {
            flash.message = message(code: 'default.not.found.message', args: [message(code: 'book.label', default: 'Book'), params.id])
            redirect(action: "list")
            return
        }

        if (params.version) {
            def version = params.version.toLong()
            if (bookInstance.version > version) {
                bookInstance.errors.rejectValue("version", …
