Question

我正在尝试为智能合约生成java Wrapper，但由于此错误而失败：

Exception in thread "main" java.lang.IllegalArgumentException: not a valid name: Main.sol:main

我按照这个人说的去除了这个错误

并为每个空属性提供默认名称（按字母顺序排列），如下所示：

[{"constant":true,"inputs":
[{"name”:”a”,”type":"bytes32"}],"name":"ApprovedTAs","outputs":
[{"name":"Trade_id","type":"bytes32"},{"name":"Trade_producer","type":"address"},{"name":"Trade_consumer","type":"address"},{"name":"Trade_rate","type":"uint256"},{"name":"Trade_from","type":"uint256"},{"name":"Trade_to","type":"uint256"},{"name":"Trade_broker","type":"address"},{"name":"Trade_topic","type":"uint256"},{"name":"approvedByA","type":"bool"},{"name":"approvedByB","type":"bool"}],"payable":false,"type":"function"},{"constant":true,"inputs":[{"name”:”b”,”type":"address"},{"name”:”c”,”type":"uint256"}],"name":"offersByProducer","outputs":[{"name":"offer_id","type":"uint256"},{"name":"offer_producer","type":"address"},{"name":"offer_topic","type":"uint256"},{"name":"offer_rate","type":"uint256"},{"name":"offer_from","type":"uint256"},{"name":"offer_to","type":"uint256"},{"name":"offer_broker","type":"address"}],"payable":false,"type":"function"},{"constant":true,"inputs":[],"name":"getAll","outputs":[{"name”:”d”,”type":"address[]"},{"name”:”e”,”type":"address[]"},{"name”:”f”,”type":"address[]"}],"payable":false,"type":"function"},{"constant":false,"inputs":[{"name":"mk_producer","type":"address"},{"name":"mk_topic","type":"uint256"},{"name":"mk_rate","type":"uint256"},{"name":"mk_from","type":"uint256"},{"name":"mk_to","type":"uint256"},{"name":"mk_broker","type":"address"}],"name":"mkOrder","outputs":[],"payable":false,"type":"function"},{"constant":true,"inputs":[{"name”:”g”,”type":"uint256"}],"name":"offers","outputs":[{"name":"offer_id","type":"uint256"},{"name":"offer_producer","type":"address"},{"name":"offer_topic","type":"uint256"},{"name":"offer_rate","type":"uint256"},{"name":"offer_from","type":"uint256"},{"name":"offer_to","type":"uint256"},{"name":"offer_broker","type":"address"}],"payable":false,"type":"function"},{"constant":false,"inputs":[{"name":"ofr_topic","type":"uint256"},{"name":"ofr_rate","type":"uint256"},{"name":"ofr_from","type":"uint256"},{"name":"ofr_to","type":"uint256"},{"name":"ofr_broker","type":"address"}],"name":"offer","outputs":[],"payable":false,"type":"function"},{"constant":true,"inputs":[{"name”:”h”,”type":"uint256"},{"name”:”ii”,”type":"uint256"}],"name":"allAdd","outputs":[{"name”:”j”,”type":"address"}],"payable":false,"type":"function"},{"constant":false,"inputs":[{"name":"sndC_id","type":"bytes32"},{"name":"sndC_producer","type":"address"},{"name":"sndC_broker","type":"address"},{"name":"sndC_topic","type":"uint256"},{"name":"sndC_from","type":"uint256"},{"name":"sndC_to","type":"uint256"},{"name":"sndC_count","type":"uint256"}],"name":"sendCCube","outputs":[{"name”:”l”,”type":"bool"}],"payable":false,"type":"function"},{"constant":false,"inputs":[{"name":"id","type":"bytes32"}],"name":"agreeTA","outputs":[{"name”:”m”,”type":"bool"}],"payable":false,"type":"function"},{"constant":false,"inputs":[{"name":"sndP_id","type":"bytes32"},{"name":"sndP_broker","type":"address"},{"name":"sndP_topic","type":"uint256"},{"name":"sndP_from","type":"uint256"},{"name":"sndP_to","type":"uint256"},{"name":"sndP_count","type":"uint256"}],"name":"sendPCube","outputs":[{"name”:”n”,”type":"bool"}],"payable":false,"type":"function"},{"constant":true,"inputs":[{"name”:”o”,”type":"bytes32"}],"name":"CreatedTAs","outputs":[{"name":"Trade_id","type":"bytes32"},{"name":"Trade_producer","type":"address"},{"name":"Trade_consumer","type":"address"},{"name":"Trade_rate","type":"uint256"},{"name":"Trade_from","type":"uint256"},{"name":"Trade_to","type":"uint256"},{"name":"Trade_broker","type":"address"},{"name":"Trade_topic","type":"uint256"},{"name":"approvedByA","type":"bool"},{"name":"approvedByB","type":"bool"}],"payable":false,"type":"function"},{"constant":false,"inputs":[{"name":"nkname","type":"string"},{"name":"code","type":"uint256"}],"name":"register","outputs": [{"name”:”p”,”type":"bool"}],"payable":false,"type":"function"}]

但错误仍然相同。我也改变了合同的名称，而不是＆＃34; main＆＃34;但没有任何改变。

我还更改了每个变量名称都有数字，特殊字符，甚至以_开头但仍然无效。

知道我应该改变什么来解决这个错误

谢谢

如果您声明仅包含参数类型而没有名称的函数o事件，则会触发此错误。例如：

event myevent(string)

应该是

event myevent(string message);
