啓動現代編譯器時出錯

在我的servlet中，使用Tomcat 5.0和JRE的版本是1.5.0，但是當我單擊URL時發生錯誤。當我創建我的項目的戰爭文件，並部署在tomcat比它工作正常。這意味着，只用我的Eclipse配置啓動現代編譯器時出錯

以供將來參考，您應該格式化控制檯輸出代碼（縮進四個空格，或者只是選擇並點擊編輯窗口上方的「101/010」圖標）。在這種情況下，我已經爲你做了這件事。 – 2010-04-05 10:03:07

錯誤消息顯示在堆棧跟蹤：

Caused by: java.lang.VerifyError: class com.sun.tools.javac.jvm.Target overrides final method . 
    at java.lang.ClassLoader.defineClass1(Native Method) 
    at java.lang.ClassLoader.defineClass(Unknown Source) 
    at java.security.SecureClassLoader.defineClass(Unknown Source) 
    at org.apache.catalina.loader.WebappClassLoader.findClassInternal(WebappClassLoader.java:1634)

的問題是，你的「的javac」是與運行時不兼容，可能是因爲您正在運行JVM已加載的另一個Java編譯器。

如果你正在使用MyEclipse（不清楚），也許看看這個blog post。基本上，您可能需要將Tomcat使用的VM與Eclipse內部使用的VM對齊。

我做了鏈接中給出的變化，但仍然。我得到相同的錯誤。 – saloni 2010-04-05 12:10:02

告訴我們您的tomcat正在使用哪個jvm，然後告訴我們您的MyEclipse正在使用哪個jvm。 – John 2010-04-06 12:52:58

我的問題解決了。我使用錯誤的JRE。謝謝 – saloni 2010-04-07 10:47:18

注意的以下內容：

CP = d：\軟件設置\雅加達Tomcat的5.0.28 \ common \ lib文件\命名-resources.jar

CP = d：\軟件設置\雅加達Tomcat的5.0.28 \ common \ lib文件\ servlet的api.jar文件

CP = d：\軟件設置\雅加達Tomcat的5.0.28 \ common \ lib文件\的tools.jar

cp = D：\ software％20setups \ jakarta-tomc在-5.0.28 \ BIN \ bootstrap.jar

CP = C：\ PROGRAM％20Files \的Java \ jre1.5.0_09 \ lib中\分機\ dnsns.jar

的的VerifyError表示版本被調用的javac編譯器與您的JDK不兼容。我的猜測是，先前/後來的JDK版本中的tools.jar被複制到了Tomcat的common/lib目錄中，common/lib中的tools.jar與當前的JDK衝突。

我不知道爲什麼tools.jar存在於你的common/lib目錄下，那裏不需要它。（也許它是爲了能夠使用JRE而不是JDK運行Tomcat）

要麼將其取出，要麼將其從當前正在使用的JDK中複製出來， Tomcat在這個之上。

傢伙您好我也得到同樣的問題，同時運行以下

「Ant構建」，因爲我不知道這個詞的「錯誤啓動現代編譯」，所以我運行的命令與verbos日誌選項，也就是「螞蟻-v構建」，最後得到的是‘內存不足錯誤Ant構建‘問題’，因此將請增加JRE內存

所以請申請集ANT_OPTS = -Xms256m -Xmx256m

，然後運行之前’將解決問題

我在使用IntelliJ Idea IDE中的ANT構建項目時遇到過類似的問題。升級您的JDK版本..我使用jdk1.7.0_51並將其升級到jdk1.7.0_65它工作。

希望它可以幫助

乾杯

這是由於內存問題。請增加內存大小：

ANT_OPTS="-Xms512M -Xmx1024M"

希望這會有所幫助。

啓動現代編譯器時出錯
