我有一个
Java项目,使用
this driver进行串行通信.驱动程序使用Windows下的dll来创建串行端口.
该项目包含几个JUnit测试,使用“运行为 – > JUnit测试”成功完成.但是,当运行ant(和不引用本机库通过的测试)时,引用本机库的测试失败.
到目前为止,我最好的猜测是将包含本机库的目录添加到java.library.path中,但是我没有通过build.xml文件成功.
有人可以告诉(干净)解决方案吗?
这是我的build.xml:
<path id="compile.classpath"> <fileset dir="${lib}"> <include name="**/*.jar"/> </fileset> <fileset dir="${junit_home}"> <include name="**/*.jar"/> </fileset> </path> <path id="test.classpath"> <pathelement location="${bin}" /> <fileset dir="${lib}"> <include name="**/*.jar"/> </fileset> <fileset dir="${junit_home}"> <include name="**/*.jar"/> </fileset> </path> <target name="compile"> <mkdir dir="${bin}" /> <echo Message="Compiling src folder..." /> <javac includeantruntime="no" classpathref="compile.classpath" srcdir="${src}" destdir="${bin}" /> <echo Message="Compiling test folder..." /> <javac includeantruntime="no" classpathref="compile.classpath" srcdir="${test}" destdir="${bin}" /> </target> <target name="test"> <mkdir dir="${test.reports}" /> <junit fork="yes" printsummary="yes" haltonfailure="yes"> <test name="${test.class.name}" todir="${test.reports}" /> <formatter type="xml" /> <classpath refid="test.classpath" /> </junit> </target>
这里是测试报告的一部分(以XML格式):
<testcase classname="nl.timo.comport.test.buildservertests.ComportFactoryTest" name="testGetInstance" time="0.0" /> <testcase classname="nl.timo.comport.test.buildservertests.ComportFactoryTest" name="testCreateDefaultComport" time="0.016"> <error message="giovynet.nativelink.SerialPort.getStateSerialPortC(Ljava/lang/String;)Ljava/lang/String;" type="java.lang.UnsatisfiedLinkError">java.lang.UnsatisfiedLinkError: giovynet.nativelink.SerialPort.getStateSerialPortC(Ljava/lang/String;)Ljava/lang/String; at giovynet.nativelink.SerialPort.getStateSerialPortC(Native Method) at giovynet.nativelink.SerialPort.getFreeSerialPort(SerialPort.java:50) at package.comport.GioComport.getFreeSerialPorts(Unknown Source) at package.comport.GioComport.findDevice(Unknown Source) at package.comport.GioComport.<init>(Unknown Source) at package.comport.ComportFactory.createNewPort(Unknown Source) at package.comport.ComportFactory.createComport(Unknown Source) at package.comport.test.buildservertests.ComportFactoryTest.testCreateDefaultComport(Unknown Source) </error> </testcase> <testcase classname="nl.timo.comport.test.buildservertests.ComportFactoryTest" name="testCreateComportWithWrongSettings" time="0.0"> <error message="giovynet.nativelink.SerialPort.getStateSerialPortC(Ljava/lang/String;)Ljava/lang/String;" type="java.lang.UnsatisfiedLinkError">java.lang.UnsatisfiedLinkError: giovynet.nativelink.SerialPort.getStateSerialPortC(Ljava/lang/String;)Ljava/lang/String; at giovynet.nativelink.SerialPort.getStateSerialPortC(Native Method) at giovynet.nativelink.SerialPort.getFreeSerialPort(SerialPort.java:50) at package.comport.GioComport.getFreeSerialPorts(Unknown Source) at package.comport.GioComport.findDevice(Unknown Source) at package.comport.GioComport.<init>(Unknown Source) at package.comport.ComportFactory.createNewPort(Unknown Source) at package.comport.ComportFactory.createComport(Unknown Source) at package.comport.test.buildservertests.ComportFactoryTest.testCreateComportWithWrongSettings(Unknown Source) </error> </testcase> <system-out><![CDATA[]]></system-out> <system-err><![CDATA[java.lang.UnsatisfiedLinkError: no libSerialPort in java.library.path at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1738)
解决方法
junit task in Ant,允许设置系统属性,就像其他一些任务一样.您需要在sysproperty嵌套元素中指定java.library.path值:
<junit fork="yes" printsummary="yes" haltonfailure="yes"> <test name="${test.class.name}" todir="${test.reports}" /> <formatter type="xml" /> <classpath refid="test.classpath" /> <sysproperty key="java.library.path" value="put your library path here"/> </junit>
