私は IntelliJ プラグインに取り組んでおり、Apache httpcore-4.2.1.jar を使用しています。Jetbrains が Confluence ページで述べているように、プラグイン構造のドキュメントに従い、この構造を使用しています。
.IntelliJIDEAx0
plugins
Sample
lib
libfoo.jar
libbar.jar
classes
com/foo/.....
...
...
META-INF
plugin.xml
私のディレクトリ構造はこれです
c:\Program Files (x86)\JetBrains\IntelliJ IDEA 12.0.1
plugins
myplugin
lib
commons-codec-1.6.jar
commons-logging-1.1.1.jar
httpclient-4.2.1-atlassian-2.jar
httpcore-4.2.1.jar
jackson-core-asl-1.9.12.jar
jackson-mapper-asl-1.9.12.jar
list.txt
myplugin.jar
META-INF
plugin.xml
com/..... #classes here
次に、myplugin.jar を使用してハードドライブから IntelliJ/Settings/Plugins/Install 経由でこのプラグインをインストールしました。
再起動後、この例外が発生しました

IntelliJ はプラグインのクラスローダーのクラスパスに他のライブラリを配置していないようで、その理由がわかりません。
誰か助けてくれませんか？
ありがとう
