启动现代编译时出错

时间：2010-04-05 09:59:34

标签： java eclipse tomcat compiler-construction ant

在我的servlet中，我使用的是Tomcat 5.0，而JRE是1.5.0但是当我点击URL时它会出错。 就像我创建一个我的项目的war文件并在tomcat中部署它工作正常。这意味着我的eclipse配置只有问题

错误是： -

大家好，我在运行以下内容时也遇到了同样的问题

“ant build”，因为我不知道这个术语“启动现代编译器时出错”所以我运行带有verbos日志选项的命令，即“ant -v build”，最后得到“Out of memory error”，所以在申请之前请增加JRE内存

所以请申请 设置ANT_OPTS = -Xms256m -Xmx256m

然后运行“ant build”问题将得到解决

问题是你的'javac'与运行时不兼容，可能是因为你正在运行一个与JVM已经加载的java编译器不同的java编译器。

如果您正在使用MyEclipse（不清楚），请查看此blog post。基本上，您可能需要将Tomcat使用的VM与Eclipse中使用的VM对齐。

注意到以下内容：

  

cp = D：\ software setups \ jakarta-tomcat-5.0.28 \ common \ lib \ naming-resources.jar

     

cp = D：\ software setups \ jakarta-tomcat-5.0.28 \ common \ lib \ servlet-api.jar

     

cp = D：\ software setups \ jakarta-tomcat-5.0.28 \ common \ lib \ tools.jar

     

CP = d：\软件％20setups \雅加达Tomcat的5.0.28 \ BIN \ bootstrap.jar

     

CP = C：\程序％20Files \爪哇\ jre1.5.0_09 \ lib中\分机\ dnsns.jar

VerifyError指示正在调用的javac编译器的版本与您的JDK不兼容。我的猜测是来自之前/之后的JDK版本的tools.jar被复制到Tomcat的common / lib目录中，而common / lib中的tools.jar与当前JDK中的tools.jar冲突。

我不知道为什么too​​ls.jar存在于你的common / lib目录中，不应该在那里需要它。 （也许是为了能够用JRE而不是JDK运行Tomcat而放在那里）

要么把它取出，要么真的需要它，从正在使用的当前JDK中复制一个来运行Tomcat。

我在使用IntelliJ Idea IDE中的ANT构建项目时遇到了类似的问题。 升级您的JDK版本..我使用jdk1.7.0_51并将其升级到jdk1.7.0_65它有效。

希望有所帮助

这是由于内存问题。请增加内存大小：

ANT_OPTS="-Xms512M -Xmx1024M"

希望这有帮助。

答案 6 :(得分：0)

这很奇怪，不应该发生。但是我的一个项目遇到了同样的错误。我加了

-Xmx1024m

在运行时 conf 并且它起作用了。我知道这需要针对“OutOfMemory 问题”完成，但它在这里也有效。 奇怪..
