java Gephi无法导入Neo4j数据

Question

我在尝试将Neo4j数据库导入Gephi时收到了以下消息：

org.neo4j.kernel.impl.storemigration.UpgradeNotAllowedByConfigurationException: Failed to start Neo4j with an older data store version. To enable automatic upgrade, please set configuration parameter "allow_store_upgrade=true" at org.neo4j.kernel.impl.storemigration.ConfigMapUpgradeConfiguration.checkConfigurationAllowsAutomaticUpgrade(ConfigMapUpgradeConfiguration.java:41) at org.neo4j.kernel.impl.storemigration.StoreUpgrader.attemptUpgrade(StoreUpgrader.java:50) at org.neo4j.kernel.impl.nioneo.store.NeoStore.tryToUpgradeStores(NeoStore.java:170) at org.neo4j.kernel.impl.nioneo.store.NeoStore.checkVersion(NeoStore.java:137) at org.neo4j.kernel.impl.nioneo.store.CommonAbstractStore.(CommonAbstractStore.java:104) at org.neo4j.kernel.impl.nioneo.store.AbstractStore.(AbstractStore.java:120) at org.neo4j.kernel.impl.nioneo.store.NeoStore.(NeoStore.java:78) at org.neo4j.kernel.impl.nioneo.xa.NeoStoreXaDataSource.(NeoStoreXaDataSource.java:165) at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:57) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:45) at java.lang.reflect.Constructor.newInstance(Constructor.java:526) at org.neo4j.kernel.impl.transaction.XaDataSourceManager.create(XaDataSourceManager.java:77) at org.neo4j.kernel.impl.transaction.TxModule.registerDataSource(TxModule.java:152) Caused: org.neo4j.graphdb.TransactionFailureException: Could not create data source [nioneodb], see nested exception for cause of error at org.neo4j.kernel.impl.transaction.TxModule.registerDataSource(TxModule.java:158) at org.neo4j.kernel.GraphDbInstance.start(GraphDbInstance.java:105) at org.neo4j.kernel.EmbeddedGraphDbImpl.(EmbeddedGraphDbImpl.java:190) at org.neo4j.kernel.EmbeddedGraphDatabase.(EmbeddedGraphDatabase.java:80) at org.neo4j.kernel.EmbeddedGraphDatabase.(EmbeddedGraphDatabase.java:64) at org.gephi.desktop.neo4j.ui.util.Neo4jUtils.localDatabase(Neo4jUtils.java:43) at org.gephi.desktop.neo4j.Neo4jMenuAction$FullImportMenuAction.actionPerformed(Neo4jMenuAction.java:218) at javax.swing.AbstractButton.fireActionPerformed(AbstractButton.java:2018) at javax.swing.AbstractButton$Handler.actionPerformed(AbstractButton.java:2341) at javax.swing.DefaultButtonModel.fireActionPerformed(DefaultButtonModel.java:402) at javax.swing.DefaultButtonModel.setPressed(DefaultButtonModel.java:259) at javax.swing.AbstractButton.doClick(AbstractButton.java:376) at javax.swing.plaf.basic.BasicMenuItemUI.doClick(BasicMenuItemUI.java:833) at javax.swing.plaf.basic.BasicMenuItemUI$Handler.mouseReleased(BasicMenuItemUI.java:877) at java.awt.Component.processMouseEvent(Component.java:6505) at javax.swing.JComponent.processMouseEvent(JComponent.java:3320) at java.awt.Component.processEvent(Component.java:6270) at java.awt.Container.processEvent(Container.java:2229) at java.awt.Component.dispatchEventImpl(Component.java:4861) at java.awt.Container.dispatchEventImpl(Container.java:2287) at java.awt.Component.dispatchEvent(Component.java:4687) at java.awt.LightweightDispatcher.retargetMouseEvent(Container.java:4832) at java.awt.LightweightDispatcher.processMouseEvent(Container.java:4492) at java.awt.LightweightDispatcher.dispatchEvent(Container.java:4422) at java.awt.Container.dispatchEventImpl(Container.java:2273) at java.awt.Window.dispatchEventImpl(Window.java:2719) at java.awt.Component.dispatchEvent(Component.java:4687) at java.awt.EventQueue.dispatchEventImpl(EventQueue.java:735) at java.awt.EventQueue.access$200(EventQueue.java:103) at java.awt.EventQueue$3.run(EventQueue.java:694) at java.awt.EventQueue$3.run(EventQueue.java:692) at java.security.AccessController.doPrivileged(Native Method) at java.security.ProtectionDomain$1.doIntersectionPrivilege(ProtectionDomain.java:76) at java.security.ProtectionDomain$1.doIntersectionPrivilege(ProtectionDomain.java:87) at java.awt.EventQueue$4.run(EventQueue.java:708) at java.awt.EventQueue$4.run(EventQueue.java:706) at java.security.AccessController.doPrivileged(Native Method) at java.security.ProtectionDomain$1.doIntersectionPrivilege(ProtectionDomain.java:76) at java.awt.EventQueue.dispatchEvent(EventQueue.java:705) at org.netbeans.core.TimableEventQueue.dispatchEvent(TimableEventQueue.java:158) [catch] at java.awt.EventDispatchThread.pumpOneEventForFilters(EventDispatchThread.java:242) at java.awt.EventDispatchThread.pumpEventsForFilter(EventDispatchThread.java:161) at java.awt.EventDispatchThread.pumpEventsForHierarchy(EventDispatchThread.java:150) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:146) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:138) at java.awt.EventDispatchThread.run(EventDispatchThread.java:91)

奇怪的是，配置参数“allow_store_upgrade=true”已经设置为true。 我使用的是neo4j-community-2.0.0-M06，Java版本是：

java version "1.7.0_45" Java(TM) SE Runtime Environment (build 1.7.0_45-b18) Java HotSpot(TM) 64-Bit Server VM (build 24.45-b08, mixed mode)

我该怎么办？Java版本是最新的，所以Neo4j
