构建 : Unable to write output 时发生 Java 错误

Question

我正在尝试构建我的项目，但它不起作用。我的源 build.xml:

<?xml version="1.0" encoding="UTF-8"?>
<project name="Optin" default="package" basedir=".">

<path id="master-classpath">
    <fileset dir="lib">
        <include name="**/*"/>
    </fileset>
</path>

<path id="test-lib">
    <fileset dir="test-lib">
        <include name="**/*"/>
    </fileset>
</path>

<!-- Cleans previous builds -->
<target name="clean">

    <echo message="Cleaning older builds..."/>

    <!-- Cleans the work folder -->
    <delete includeemptydirs="true">
        <fileset dir="work" includes="**/*"/>
        <fileset dir="build" includes="**/*"/>
    </delete>

</target>

<!-- Compiles the classes -->
<target name="compile" depends="clean">

    <echo message="Compiling..."/>

    <mkdir dir="build/classes"/>
    <javac includeantruntime="false" srcdir="src" destdir="build/classes" compiler="javac1.7" target="1.7">

    <javac includeantruntime="false" srcdir="tests" destdir="build/tests" compiler="javac1.7" target="1.7">

        <classpath refid="test-lib" />
    </javac>

</target>

<target name="tests" depends="compile">

    <junit printsummary="yes" haltonfailure="true">

            </fileset>
        </batchtest>

    </junit>

</target>

<!-- Prepares the package to go -->
<target name="package" depends="tests">
    <echo message="Packing..."/>

    <!-- Gets the timestamp of this build -->
    <tstamp>
        <format property="timestamp" pattern="yyyyMMdd_HHmmss"/>
    </tstamp>

    <input message="Please select the target environment:" addproperty="destenv" defaultvalue="dev" validargs="dev,fqa"/>

    <!-- Creates the jar -->
    <mkdir dir="work/bin"/>
    <jar destfile="work/bin/optin.jar" basedir="build/classes">
        <manifest>
            <attribute name="Main-Class" value="com.vilt.tim.optin.App"/>
        </manifest>
    </jar>

    <!-- Creates the directory structure -->
    <mkdir dir="work/conf"/>
    <mkdir dir="work/lib"/>
    <mkdir dir="work/logs"/>
    <mkdir dir="work/input"/>
    <mkdir dir="work/output"/>

    <!-- Copies the additional resources -->
    <copy todir="work">
        <fileset dir="resources/pack">
            <include name="*.*"/>
        </fileset>
    </copy>

    <!-- Copies the related properties -->
    <copy todir="work/conf">
        <fileset dir="properties/${destenv}">
            <include name="*.*"/>
        </fileset>
    </copy>

    <copy todir="work/lib">
        <fileset dir="lib">
            <include name="**/*"/>
        </fileset>
    </copy>

    <!-- Creates the package -->
    <zip destfile="package/${timestamp}_optin_build.zip" basedir="work" update="false" level="9"/>

    <!-- Clean everything at the end -->
    <antcall target="clean"></antcall>

</target>

但是当我运行它时，出现以下错误:

Buildfile: C:\Users\renato.silva\git\optin\build.xml
clean:

BUILD FAILED
C:\Users\renato.silva\git\optin\build.xml:52: Unable to write output

 Total time: 1 second

但是当我单独运行测试类时，它工作正常。我正在使用 Spring 注释:

import org.junit.Assert;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import    org.springframework.test.context.support.AnnotationConfigContextLoader;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(loader=AnnotationConfigContextLoader.class)
public class AppTest {  

@Test
public void test(){

    Assert.assertTrue(true);

     }

}

我错过了什么？

PS:当我注释目标测试行时，构建可以正常工作，但是当我运行 java -jar 时，会发生以下错误:

Error: Could not find or load main class .

我不确定这些错误是否相关。

Answer 1

缺少以下行:

<mkdir dir="test-report"/>

现在完美运行!
