使用SWT附加组件时出现java.lang.NoClassDefFoundError(AutocompleteComboInput) [英] java.lang.NoClassDefFoundError while using SWT Add-on (AutocompleteComboInput)

问题描述

我正在尝试使用 net.sf.swtaddons_0.1.1_bin_src .jar 通过添加外部JAR"添加到库中.

I am trying to implement an autocomplete Combo in SWT using AutocompleteComboInput. I have added net.sf.swtaddons_0.1.1_bin_src.jar to the library via "Add External JAR".

import net.sf.swtaddons.autocomplete.combo.AutocompleteComboInput;
...

subjectCodeCombo = new Combo(tab3Composite, SWT.DROP_DOWN);
// other code modifying Combo appearance here...

// returns a String[] of items retrieved from database
String[] subjectCodeArray = dbQuery.subjectsToArray();

subjectCodeCombo.setItems(subjectCodeArray);
subjectCodeCombo.setText("- SELECT -");
new AutocompleteComboInput(subjectCodeCombo); // throws an error

但是，我得到一个NoClassDefFoundError.如我所读，似乎在运行时未找到类.

However, I am getting a NoClassDefFoundError. As I have read, it seems a class is not found during runtime.

我相信我需要对运行时类路径"做一些事情，但是我迷路了.赞赏如何在Eclipse IDE中解决此问题的步骤.

I believe I need to do something about the "runtime classpath", but I am lost. Steps on how to resolve this in Eclipse IDE is appreciated.

推荐答案

我已经找到了解决此问题的方法.

I have found the solution to this problem.

除了net.sf.swtaddons_0.1.1_bin_src.jar之外，还需要将其他3个JAR添加到库中:

Apart from net.sf.swtaddons_0.1.1_bin_src.jar, 3 other JARs were still needed to be added to the Library:

• eclipse-equinox-common-3.5.0.jar
• org.eclipse.core.commands.jar
• org.eclipse.jface-3.6.0.jar
